PLASTIC ENGINE PARTS

To decrease an automobile’s weight, and thus improve its fuel efficiency, more and more parts are now made of plastic – but usually not critical engine components. Because of high stress and heat most engine parts are still made of metal. Now, in Britain, an intake manifold – the engineblock attachment that feeds air and fuel from the carburetor to the cylinders

– has been molded from plastic. Its developers are Fibeiglass, Ltd., of St.

Helens, Merseyside, BTR Permali RP, Ltd., of Gloucester, and Ford Motor Co. Ltd., of Essex. The new manifold is believed to be the first major plastic engine component ever to be designed for production automobiles. It is made by polyester compound – called – and is shaped exactly like an aluminum manifold currently used on the Ford Cortina’s 1.3-liter engine. Since this part has a series of intricate, twisting interior chambers, a new molding technique had to be devised. The trick is to form the plastic

around metal cores inside a mold. Once the manifold is set, or cured, it is placed in a hot oil bath that melts the metal cores, leaving the required hollow chambers.

The 21/2 -pound plastic manifold weighs 25 per cent less than a metal

TYPES OF FUELS

There are three basic types of fuels for motor vehicles. There is diesel fuel, there is petrol and there is two-stroke mixture. Most motorcycles have two-stroke petrol engine. There are motorcycles with four-stroke petrol engines; there are no motorcycles with diesel engines.

A few cars have diesel engines. There are also few cars with twostroke engines but most cars have four-stroke petrol engines. Most lorries have diesel engines. There are a few lorries with four-stroke petrol engines but there are no lorries with two-stroke petrol engines.

There is a lot of carbon (about 85%) in diesel fuel. There is also a lot of carbon in petrol. There is also a little sulphur (about 1%) in diesel fuel but there is no sulphur in petrol.

Two-stroke mixture is about 95% petrol and 5% oil. There is no oil in the fuel for four stroke engines.
