VW Golf 4 and Bora – Motors

A wide range of engines is available for the VW Golf and Bora drive: from a direct injection four-cylinder diesel engine, 1,9 SDI with the power of 68 KM, and a four-cylinder gasoline engine 1,4 with power 75 KM, via a turbo diesel engine 1,9 TDI and many varieties of gasoline engines with varying power, all the way to the flagship model 4 Motion with V6 gasoline engine displacement 2,8 liter and power 204 KM.

Four-wheel drive version – 4 Motion, touted by VW as "flawless driving pleasure”, is offered with gasoline engines 1,8 l/ 125 KM, 2,3 l/150 KM, mentioned above 2,8 l/ 204 KM and diesel engine 1,9 l/ 90 KM. High engine performance does not have to mean that they are not economical, the best example of which is the engine 1,9 TDI. It provides a very dynamic driving with low fuel consumption. Model with engine 1.9 TDI (66 kW / 90 KM) and with a mechanical gearbox it consumes an average of 100 km only 4.9 liter of diesel fuel (according to the EU standard 93/116). All engines are liquid-cooled, located crosswise to the direction of travel at the front and suspended from the top left and right on rubber-metal bearings. This allows them to swing like a pendulum. The forces that arise as a result are absorbed by the support at the bottom. Such a solution makes, that engine vibrations are transferred to the body to a minimum, which increases driving comfort.

Engine blocks 1.4 i 1.6 liters are made of aluminum, with fused gray cast iron cylinder liners. All other engines have cast iron blocks. The die-cast aluminum cylinder head is bolted to the engine block. Steel seats and valve guides are pressed into the head. A light alloy sump is placed under the engine, in which the oil necessary for lubricating and cooling the engine is collected.

The cylinder head in gasoline engines works on the principle of lateral flows: fresh air-fuel mixture flows in on one side, and the exhaust gas flows out on the opposite side. In this way, a quick exchange of gases through the intake and exhaust valves is guaranteed. The valve clearances are hydraulically regulated, thus eliminating the need to adjust clearances during technical inspections.

All engines have a poly V-belt, which drives the alternator, power steering pump and air conditioning compressor.

The maintenance-free electronic engine control system takes care of the preparation of the correct composition of the fuel-air mixture and the ignition. As a result, during the technical inspection, the need to manually adjust the ignition advance angle and the idle speed was eliminated. Instead, the spark plugs and air filter must be replaced regularly.

To make sure, which of the wide range of engines is installed in your Golf, look at the warranty book or the car's documents, A plate with all the technical data of the car is located in the trunk, in the spare wheel well. Placed on it 6 basic data from the warranty book and serial number. Volkswagen identifies its engines with three letters and six numbers. After producing over 999 999 copies of a given type of engine, the first digit is replaced by a letter.
