car intake system
Your vehicle's air intake system draws air from outside into the engine. But do you know exactly how it works? Here's what you need to know. There are a handful of car owners who aren't entirely sure what an air intake system does, how it works, and how important it is to a car. In the 1980s, the first air intake systems were offered, which consisted of molded plastic intake tubes and a cone-shaped cotton gauze air filter. Ten years later, foreign manufacturers began to import popular Japanese air intake system designs for the compact sports car market. Now, thanks to technological advances and the ingenuity of engineers, intake systems are available as metal tubes, allowing for a greater degree of customization. The pipes are usually powder coated or painted to match the color of the vehicle.Now,…
Inlet valve
In this edition we will talk about intake and exhaust valves, however, before going into details, we will put these elements in context for a better understanding. The engine needs a means to distribute the intake and exhaust gases, to control and move them through the manifold to the intake manifold, combustion chamber and exhaust manifold. This is achieved through a series of mechanisms that form a system called distribution. An internal combustion engine requires a fuel-air mixture, which, when burned, drives the mechanisms of the engine. In the manifold, the air is filtered and sent to the intake manifold, where the fuel mixture is metered through systems such as a carburetor or injection. The finished mixture enters the combustion chamber, where this gas burns and, thus, converts thermal energy into mechanical energy. After finishing…
The car starts and stalls immediately or after a few seconds: what to do?
The situation when the car engine starts, and after a few seconds it stalls, is familiar to many drivers. It usually takes you by surprise, confuses and makes you nervous. To begin with, calm down and first check the obvious things: Fuel level. This may seem silly to some, but when the head is loaded with many problems, it is quite possible to forget about the simplest. Battery charge. With a dead battery, some components, such as a fuel pump or ignition relay, may malfunction. Check what kind of fuel is poured into the tank of your car. To do this, pour a little into a transparent container and leave to settle for two to three hours. If the gasoline contains water, it will gradually separate and end up at the bottom. And if there are foreign impurities, sediment will appear at the bottom. ...
Cleaning the throttle valve - step by step instructions. Check out how to clean the throttle valve!
Causes of Dirt in a Throttle Body The first reason a throttle body collects dirt has to do with its location and role in the vehicle. As we mentioned in the introduction, it is located next to the engine. Due to the fact that its task is to pass air, it is constantly exposed to transporting external dirt, which can cause valve failure. This will be due to another damaged or dirty element - the air filter. Dirt gets into the throttle valve and on the other side from the engine. This is primarily exhaust gases, oil or soot (soot). How does a dirty throttle affect a car? Dirt accumulating on the throttle body negatively affects the operation of the car. First of all, it blocks the free opening and ...
Intake manifold - how to properly care for the engine manifold in a car?
Intake manifold - design Depending on the car model, this element differs in design. As a rule, the manifold is a metal or plastic pipe, the purpose of which is to supply air or a fuel-air mixture to the head with the lowest possible hydraulic resistance. The engine intake manifold consists of channels, the number of which usually corresponds to the number of combustion chambers. Engine manifold and intake system The entire intake system contains many other devices and parts that work with the engine manifold. These include the throttle valve, which provides additional air intake depending on the engine speed and demand. In units with indirect gasoline injection, the injectors responsible for fuel dosing are also located in the air manifold. In turbocharged cars, before this…
What is a choke? Symptoms of a breakdown and the cost of repairing a damaged throttle body
As the name suggests, the throttle valve has a lot to do with controlling the throttle valve. But what? Read our text and learn more about this mechanism. How does the throttle valve work? What are the warning signs that it is damaged? How much will it cost to repair it? We will answer all these questions, so if you want to know more, start reading! Throttle - what is it? The damper is a type of throttle valve that regulates the air flow due to a disk rotating around its own axis. The movement of the blade inside causes the medium inside to be supplied further in the required quantity. In car engines, the throttle valve is often a separate component. It was already used in steam locomotives, so this is by no means…
Intake Manifold: When it twitches, brakes and drips...
Today, supplying the engine with air has become a real science. Where an intake pipe with an air filter was once enough, today a complex assembly of many components is used. In the case of a faulty intake manifold, this can become noticeable primarily by loss of performance, heavy pollution, oil leaks. The main reason for this complication is the modern engine management system with an exhaust gas aftertreatment system. Modern engines are supplied with air through intake manifolds (another term is "intake plenum"). But as technology complexity increases, so does the risk of defects. Structure of the intake manifold The intake manifold consists of a one-piece tubular cast aluminum or gray cast iron. Depending on the number of cylinders, four or six pipes are combined into the intake manifold. They converge at the central point of the water intake. There are several additional components in the intake manifold:…
How to check the choke on a carbureted engine

The throttle valve is a plate in a carburetor that opens and closes to let more or less air into the engine. Like a throttle valve, the throttle valve rotates from a horizontal to a vertical position, opening up a passage and allowing more air to pass through. The choke valve is located in front of the throttle valve and controls the total amount of air entering the engine. The throttle is used only when starting a cold engine. During a cold start, the choke must be closed to limit the amount of incoming air. This increases the amount of fuel in...
Symptoms of a Bad or Faulty Accelerator Cable
Common signs include exterior coating damage, slow throttle response, and cruise control problems. While most new cars use electronic throttle control, physical accelerator cables are still widely used in many vehicles on the road. The accelerator cable, sometimes referred to as the throttle cable, is a metal-braided cable that serves as the mechanical link between the accelerator pedal and the engine throttle. When you press the gas pedal, the cable stretches and opens the throttle. Because the throttle controls the car's power, any cable problems can quickly lead to vehicle handling problems, so it should be checked as soon as possible. The most common way accelerator cables fail is through them...
How long does the throttle position sensor last?
The throttle body in your car is a rather complex system that is part of its air intake system. The air intake system is responsible for controlling the amount of air entering the engine. In order for your engine to run properly, you need the right combination of fuel and air. Throttle operation involves a throttle position sensor, which is used to determine the position of your vehicle's gas pedal. It sends this information to the engine control unit so that the throttle position can be calculated. This is how your car determines the amount of fuel injected and the amount of air supplied to the engine. It's a big, long process, and each part depends on the others. Now that we have determined how important this throttle position sensor is…
How long will a throttle body last?

The throttle body is one of those parts. This component is part of the air intake system, a system that plays an important role in controlling the amount of air entering the engine. If the throttle body stops working or fails, the correct amount of air will not flow. This negatively affects fuel consumption. Although there is no set mileage when it comes to…
Symptoms of a Faulty or Faulty Throttle Actuator
Common symptoms include throttle oscillation, poor fuel economy, and frequent engine shutdowns. In the past, when a driver was driving uphill with extra weight in the back of the car or simply turning on the air conditioner, his right foot was the only way to increase speed. As technology has improved and more vehicles have switched from manual throttle cable to electronic throttle controllers, numerous improvements have been made to the fuel system to improve engine efficiency and driver comfort. One such component is the throttle actuator. Although it is an electric actuator, it can fail, requiring it to be replaced by a certified mechanic. What is a throttle actuator? The throttle actuator is a throttle control component that helps regulate…
Symptoms of a Faulty or Faulty Throttle Position Sensor
Common symptoms include no power when accelerating, rough or slow idling, engine stalling, inability to upshift, and the Check Engine light coming on. The Throttle Position Sensor (TPS) is part of your vehicle's fuel management system and helps ensure that the correct mixture of air and fuel is supplied to the engine. TPS provides the most direct signal to the fuel injection system about how much power the engine needs. The TPS signal is continuously measured and combined many times per second with other data such as air temperature, engine speed, mass air flow and throttle position change rate. The data collected determines exactly how much fuel to inject into the engine at any given time. If the throttle position sensor and...
Throttle valve
In modern cars, the power plant works with two systems: injection and intake. The first of them is responsible for supplying fuel, the task of the second is to ensure the flow of air into the cylinders. Purpose, main structural elements Despite the fact that the whole system “controls” the air supply, it is structurally very simple and its main element is the throttle assembly (many call it the old-fashioned throttle). And even this element has a simple design. The principle of operation of the throttle valve has remained the same since the days of carbureted engines. It blocks the main air channel, thereby regulating the amount of air supplied to the cylinders. But if earlier this damper was part of the carburetor design, then on injection engines it is a completely separate unit. Ice Supply System In addition to the main…
Diesel swirl dampers. Trouble that can destroy the engine
Swirl flaps are a solution used in many common rail diesel engines. The air turbulence it creates in the intake system just before the intake valves helps the combustion process at low speeds. As a result, the exhaust gases should be cleaner, with less nitrogen oxides. So much theory, which most likely corresponds to reality, as long as everything in the engine is completely functional and clean. As a rule, the flaps mounted on the axis change their installation angle depending on the engine speed - at low speeds they are closed so that less air gets into the cylinders, but twisted accordingly, and at high speeds they must be open. so that the engine "breathes" fully. Unfortunately, this device works in very unfavorable conditions ...
What are the typical common rail diesel engine problems? [management]
Relatively often in articles about Common Rail diesel engines, the term "typical malfunctions" is used. What does this mean and what does it entail? What should I pay attention to when buying any common rail diesel engine? At the beginning, very briefly about the design of the Common Rail fuel system. Traditional diesel has two fuel pumps - low pressure and so-called. injection, i.e. high pressure. Only in TDI (PD) engines was the injection pump replaced by the so-called. injector pump. However, Common Rail is something completely different, simpler. There is only a high pressure pump, which accumulates the fuel sucked from the tank into the fuel line / distribution rail (Common Rail), from which it enters the injectors. Because these injectors only have one...
