Glow plug for diesel engine

From the early 1990s, with many development and application of new technologies, diesel engines play more and more important role in the vehicle engines. Diesel engines outshine in the medium and heavy vehicles engines; in the field of light vehicles, diesel engines’ applications also expand; in the field of cars, the diesel cars with low fuel consumption and low emission have been growing rapidly. Especially with the stringency of environmental and energy regulations in many countries in recent years, due to the obvious advantages, diesel engines are widely used in the world.

Statistics show that in 2000 the proportion of car with diesel engine in Western Europe is 30%, while 28% for the whole f Europe. And it is estimated conservatively that the proportion of commercial vehicle will be more than 35% in 2005.

Glow plugs emerged as an auxiliary measure of cold start for diesel engine. Glow plug can not only significantly improve the cold-start performance of diesel engine, but also effectively improve the emissions targets when starting up.
