【正文】 on the heat of pressed air to ignite their fuel. When the engine is cold, pression alone may not produce enough heat for the fuel to burn, so most car and truck diesels use glow plugs, electric elements that heat up the cylinder before a cold engine is started These electric heaters are switched on for anywhere from 5 to 4 10 seconds to make the engine easier to start. They use about 15 amps each (you have one for each cylinder). This is why you need a high amperage battery. For areas with severe winters, a block heater is a good idea. Many diesels have them as standard or optional equipment. Torque is a measure of twisting force, and in the automotive world it translates to the ability to get a load moving. This makes a diesel engine good for towing, trucks and buses, but will never be great in the 0 to 60 ranges. Because of their high pression ratios, diesel engines have to be built with more durable ponents than gasoline engines. Diesel fuel is a lubricant, and as it is sprayed into the engine during the bustion cycle, it lubricates the cylinder walls. As a result, diesels are subject to less internal wear than gasoline engines, and will usually run many more miles before requiring an overhaul. It can make a car more stable, but will handle and corner differentaly than a gasoline engine. It also makes the steering heavy as well, I would remend buying a diesel car with power steering. Diesel engines are nosier than gasoline engines. If you open the hood of a gasoline car with the engine running, you know that gasoline engines are fairly quiet. With diesel engines, there39。ll be producing higher pollution levels. Diesel engines are ideal for short journeys because their efficiency is almost as high cold as when they are hot. Diesel engines last a lot longer than gasoline engines. This is because gasoline destroys lubrication and diesel fuel doesn39。ll get far below the fuel economy that you39。t need an electric ignition system, which reduces their plexity. However, they also create more noise, they can be difficult to start in extremely cold weather and they sometimes require more frequent routine maintenance than gasoline engines. Most passenger car diesel engines have a glow plug of some type. When a diesel engine is cold, the air pression may not raise the air to a high enough temperature to ignite the fuel. The glow plug is an electric heater that glows redhot and helps to ignite the fuel when the engine is cold so that the engine can start. The amount of power which an engine can produce is limited by how much fuel it can burn, and the amount of fuel it can burn is limited by the amount of oxygen in the cylinder. The amount of oxygen in the cylinder is limited by the amount of air in the cylinder. So, if more power is wanted then more air is needed, how do we achieve this? Well a large en
