Volkswagen APE engine
Content
Volkswagen concern engineers have proposed a new power unit, which is included in the EA111-1,4 engine line, including AEX, AXP, BBY, BCA, BUD and CGGB.
Description
The production of the Volkswagen APE engine has been established at the plant of the VAG concern since October 1999.
APE is a 1,4-liter gasoline in-line four-cylinder aspirated engine with a capacity of 75 hp. with and a torque of 126 Nm.
Installed on Volkswagen cars:
The cylinder block is cast from aluminum alloy.
Aluminum pistons, lightweight. They have three rings, two upper compression, lower oil scraper. Piston pins of a floating type, from longitudinal displacement, are fixed with retaining rings.
The crankshaft is mounted on five bearings, made integral with the cylinder block. It has a design feature - it cannot be removed, since loosening the caps of the main bearings leads to deformation of the block. Therefore, when the crankshaft or its main bearings are worn, the cylinder block assembly with the shaft is replaced.
The cylinder head is aluminum, with two camshafts located in a separate support and 16 valves equipped with hydraulic compensators.
Timing belt drive. In the diagram below, the drive belts are marked A - auxiliary, B - main.
The intake camshaft (inlet) is driven by the main (large) belt from the crankshaft sprocket, the exhaust camshaft is driven by the auxiliary (small) belt from the intake.
Car owners note a low service life of timing belts, especially a short one. As a rule, it does not withstand more than 30 thousand kilometers. The manufacturer recommends replacing the belts every 90 thousand km, and then carefully inspect them after passing 30 thousand km.
Fuel supply system injector, multipoint injection, Bosch Motronic ME7.5.10. It does not cause big troubles, but it is sensitive to the quality of fueled gasoline.
Combined type lubrication system. Gear oil pump, driven by the crankshaft nose.
The ignition system is electronic, non-contact with microprocessor control. Recommended candles - NGK BKUR 6ET-10.
The engine as a whole turned out to be successful, which is proved by its external characteristics,
The dependence of power and torque on the number of revolutions of the internal combustion engine presented in the graph.

Reliability, weaknesses, maintainability
Reliability
Most car owners speak positively about APE and consider it reliable with a caring attitude towards it. It is known that the main characteristics of the reliability of any motor are its resource and safety margin.
The manufacturer has set a resource of 250 thousand km for APE. In practice, with timely maintenance, it reaches 400 thousand km, and this is not the limit.
On the forums, motorists share their impressions about the reliability of internal combustion engines.
So, Max820 writes: “... the APE engine is a regular 1.4 16V with unusual controls, i.e. the Bosch MOTRONIC control system itself is quite tricky, but quite reliable. Everything is electronically controlled, including the throttle valve, i.e. no throttle cable. More on motronics. I heard from reliable and smart people that he is reliable and not capricious, unlike magnetti marelli».
And Arthur S. emphasizes the importance of service: “... cleaned the oil separator, replaced the breather with a wider one, cleaned the air filter section - there are no problems with the engine».
APE has a significant margin of safety. It can be boosted up to 200 liters. With. But for a number of reasons, this should not be done. From tuning, the resource of the motor decreases, the indicators of technical characteristics decrease. At the same time, a simple chip tuning can give a power increase of 12-15 hp. With.
Weak spots
The presence of weaknesses in the APE engine is largely determined by the negligent attitude towards it on the part of car owners and the low quality of domestic fuels and lubricants.
Problems in the fuel system are mainly due to clogged injectors and throttle. A simple flush of these nodes eliminates all troubles.
The bending of the valves and the destruction of the pistons occurs when the timing belt breaks or jumps.
The manufacturer determined the resource of belts at 180 thousand km. Unfortunately, in our operating conditions, such a figure is not realistic.
Oil starvation can cause an elementary clogging of the oil intake. Again, flushing will fix the problem.
Difficult maintenance of the engine is caused by its design features. For example, to replace the timing belt, you will have to remove the front right wheel, crankshaft pulley, valve cover and perform a number of preparatory work.
The accumulation of oil in the candle wells occurs due to the destruction of the seal (sealant) between the camshaft bearing and the block head.
Maintainability
Restoring the unit does not cause difficulties. It is repaired even in garage conditions.
Spare parts can be purchased at any specialized store, or at the "secondary". But it is not advisable to use disassembly services, since it is impossible to determine the residual life of the part.
When repairing, a lot of special tools and fixtures are used. Craftsmen find a way to reduce the cost of buying almost disposable, at the same time not cheap necessary gadgets.
On the Internet you can find a lot of useful homemade products used in the repair of the motor.
One of the alternative solutions to the issue of APE overhaul may be the purchase of a contract engine. This option sometimes turns out to be much cheaper, which is relevant for most motorists today.
The cost of a contract ICE depends on many factors and amounts to 40-100 thousand rubles, while the overhaul of the unit will cost 70-80 thousand rubles.
The Volkswagen APE engine is a simple, reliable and durable unit with strict adherence to all manufacturer's recommendations for its maintenance and operation.
