Opel 20NE, 20NEJ, 20SEH, 20XEJ engines
20NE
The 20NE engine installation was developed by the designers of General Motors. In 1986, the installation of this power unit in Opel Omega A cars began. The material for the manufacture of the cylinder block, 216,3 mm high, is cast iron. The stroke of the crankshaft and the diameter of the cylinders are 86 mm. The pistons have a height of 30,4 mm. Thanks to these indicators, an engine displacement of 2 liters is provided. The cylinder head is a single shaft type with eight valves. The intake and exhaust valves are 41,8 mm and 36,5 mm in diameter, respectively.
The toothed belt drives the gas distribution system. This element is replaced every 60 km. Neglecting this condition can lead to a broken belt, and as a result, to deformation of the valves. Since the motor uses hydraulic lifters, valve adjustment is not required. The throttle valve has a diameter of 000 mm.
20 NEJ
This power plant is very rare and was used only in the Opel Vectra B Car. It works on the use of gasoline fuel. The design of this engine has 4 cylinders and 8 valves. The power rating is 112 horsepower or 82 kW. A toothed belt is used as a drive for the gas distribution system. Cooling is carried out by a water system. The release of this motor unit was carried out from 1995 to 1998.
20 SEH
The power of this engine is 129 hp, and its working volume is 1998 cc. It has 4 cylinders arranged in a row, and 2 valves for each cylinder. The compression ratio is 10:000 and the piston stroke is 1mm. The fuel mixture is supplied to the working chambers of the cylinders by means of multi-point injection. The 86SEH power unit was installed on Opel cars of the following models: Kadett E, Ascona C and Vectra A.
20 YEARS
This engine was installed on Opel cars from 1998 to 1998. They were equipped with models such as: Opel Astra F and Opel Vectra A. 20XEJ is the only unit among the engines under consideration that has 4 valves for each cylinder. In 1988, increased control of the amount of emissions of harmful gases into the atmosphere began. The catalyst and the Lambda probe ensured compliance with the Euro-1 European environmental standard. The cylinder block is made of cast iron. Its height is 216.3 mm, the piston stroke is 86 mm, the connecting rod is 143 mm long, and the piston height is 30.43 mm.
The car on which the largest number of power plants from the line in question was installed:
Opel Vectra A
The birth of the Opel Vectra model dates back to 1988. It replaced the Ascona C. This car was produced in the following body styles: a three-door hatchback or a five-door sedan. Basically, the car differs from its predecessor by having smoother lines in the exterior of the car than the Ascona. In this regard, increased aerodynamic performance.
There is also an integrated spoiler in the trunk lid. Did the company offer several trim levels available for purchase? GL,GLS,CD and GT. In the simplest configuration, there are practically no options for comfortable movement. The GLS modification boasts higher quality interior fabric, central locking, power windows for front passengers, central locking, air conditioning, tachometer, adjustable driver's seat, rear headrests and fuel tank cap.
A more advanced instrument panel, alloy wheels, an improved interior and more equipment are present in the CD and GT versions. Also in the sports configuration with the GT index, more powerful engine installations, special gearboxes and a sports suspension were installed.
In the front suspension there are MacPherson struts and an anti-roll bar, which is mounted on a powerful subframe, together with an internal combustion engine and a gearbox. Front-wheel drive models have a semi-independent rear suspension, in which there are telescopic shock absorbers and trailing arms that are connected by a torsion beam. The use of small barrel springs made it possible to provide a decent size for the luggage compartment. In powerful and front-wheel drive models, the rear suspension is of an independent type. All Opel Vectra A vehicles are equipped with ventilated brake discs at the front and drum or disc brakes at the rear.
Speaking about the safety of this vehicle, it can be noted: safety elements of the cabin space, three-point seat belts, and a special body structure, with the presence of special deformation zones, designed to absorb impact energy. An anti-lock braking system is available as an option. For modifications GD and GT, this option is standard equipment. A special version of Frisco was delivered to the Swiss market in 1992, with a two-liter engine and a driver's airbag.
At one time, the Opel Vectra A set the standards for modernity and equipment in the global automotive market. The main competitors were Audi 80 and VW Passat. Among the main advantages, one can whiten the simplicity and reliability of the design, suitability for repair, softness of the suspension and a spacious cabin space. In these cars, wiring is often damaged, the body rots, generator and starter installations break, and the fuel pump fails.
Сonclusion
All motor installations are capable of overcoming a resource of 300 thousand km. without major repairs. But, it is worth noting that this condition will be observed only with proper maintenance. The engine number in all models is located near the crankshaft pulley.
