Engines

The two most common types of engines for cars are the petrol engine and diesel engine.

Petrol engines are usually lighter and smaller than diesel engines. This makes them cheaper, and this is why most cars use petrol engines. Petrol engines are also less noisy than diesel engines. They usually go foster. On the other hand, diesel engines use less fuel than petrol en­gines, and this is why trucks use them. They are also safer than petrol engines, because there is less danger of fire.

There are two main types of petrol engine - 4-stroke and 2-stroke. All cars use 4-stroke engines. But most motorbikes use 2-stroke engines. They are lighter and smaller than 4-stroke engines, and are there­fore cheaper.

The new vehicle was designed and built by the General Engineer­ing Division. A conventional chassis, rigid axles and leaf spring sus­pension are used in this car. However, the frame has been modified to improve the angle of turning. The rear suspension incorporates rubber spring washers. There are telescopic shock absorbers all around. This car has four-wheel drive, it is fitted with larger tires. The wheels are driven through a four-speed gearbox, third and the top gears being synchromesh. The car is also fitted with a transfer gearbox with a 1.148:1 high ratio and a 2.4:1 low ratio. This gives the car eight forward and two reverse speeds. Both front and rear axles incorporate spiral bevel differentials. Brakes are of drum type with servo assistance and the steering system is modified. The car is powered by a six-cylinder engine, which resulted in a maximum average speed of 55 miles per hour. It should be noted that ventilation is provided by means of a standard air system.
