The A-Z of Diesel returns this week as we move on the G, H and I.
G is for Glow Plug
A glow plug is perhaps best described as the diesel’s equivalent of a spark plug. When the engine is cold, the glow plug heats the combustion chamber, raising the air temperature sufficiently for the fuel to combust and the engine to start. As well as helping start the engine, glow plugs reduce emissions by ensuring an improved fuel burn and they also help reduce noise, since they help to make today’s engines more efficient.
H is for Honda
With a huge manufacturing base right here in Britain, H has to stand for Honda. Honda established their UK operation in 1985, while engine production began in 1989. The first Honda built in Britain was the Civc, which began in 1994 and by the year 2000 the plant was exporting car to Japan. Today, the latest i-DTEC 1.6 litre diesel is built in Swindon alongside the Civic and Civic tourer itself.
I is for Injection
On a Diesel engine the fuel is injected directly into the cylinder. The injector has to be able to withstand high temperature and pressure so that the fuel can be delivered as a fine mist. Diesel injectors have been the subject of many years research and experimentation and it is the improvements in injector technology have helped to underpin many of the refinements offered by modern diesel powerplants.
