how diesel engines work and combustion theory part 1 of 2 Davidsfarmison[bliptv]now 1/27/2013; 'practicalcreation' adds this useful information; Hi. There are a couple engine designs that almost eliminate the need for full ignition at 45 degrees of the piston rod. The rods never get vertical and the stroke for the second cylinder is always in the mirror position. The second engine design is the Scuderi or Miller cycle engine which fires below TDC. Can use both diesel or gas as fuel but a few problems with the heat adn the pressure on the valves.

Diesel engines by work compressing only the air. This increases the air temperature inside the cylinder to such a high degree that it ignites atomised diesel fuel that is injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to petrol), which use a spark plug to ignite an air-fuel mixture. In compression-ignition engines, glow plugs (combustion chamber pre-warmers) may be used to aid starting in cold weather, or when the engine uses a lower compression-ratio, or both. The original compression-ignition engine operates on the "constant pressure" cycle of gradual combustion and produces no audible knock.

How Diesel Engines Work! (Animation) This animation describes the working principles of diesel engines in the context of an inline-four engine that operates in a four-stroke mode. This kind of engine has four cylinders mounted in a straight line. Unlike the typical Otto-cycle engine, a diesel engine takes in only air through the intake valves during the 1st stroke. During the 2nd stroke, the intake valves are closed and the air is compressed. As the air is highly compressed in the cylinder, the temperature of the air rises and reaches almost 1300 degrees Fahrenheit. In the 3rd stroke, diesel fuel is injected directly into the cylinder. The fuel instantly ignites because of the high temperature of the air. The explosion pushes the piston down, which transfers power to the crankshaft. The 4th stroke is the process where the spent fuel-air mixture exits through the open Exhaust valves and the stroke cycle is repeated again. A big advantage of diesel engines is that they typically deliver 25-30 % better fuel economy than similarly performing gasoline engines.

Here's why diesel engines are better than gasoline engines

Why Do Diesel Engines Last So Long?
If you have heard that Diesel engines last longer than Gasoline engines and wondered why, then this is the video for you. A mechanic with 11 years of experience goes into detail as why the loud and heavy engines can go over a million miles regularly. If you have questions they can be left in the comment section.
