Meaning
Diesel is a liquid form fossil fuel or we can say that it is a liquid fuel that can be used in Diesel Engines. Unlike Petrol its engine fuel ignition takes place without any spark and in substitution to it with the help of compression. Diesel engines have found a broad use due its fuel efficiency and thermodynamic efficiency.
Uses
Unlike Gasoline and L.P.G, Diesel engines do not use spark ignition's. An engine running on diesel compresses the air inside the cylinder to high pressures and temperatures (compression ratios from 14:1 to 18:1 are common in current diesel engines); the engine generally injects the diesel fuel directly into the cylinder, starting a few degrees before top dead center (TDC) and continuing during the combustion event. The high temperatures inside the cylinder cause the diesel fuel to react with the oxygen in the mix (burn or oxidize), heating and expanding the burning mixture to convert the thermal/pressure difference into mechanical work, i.e., to move the piston. Engines have glow plugs and grid heaters to help start the engine by preheating the cylinders to a minimum operating temperature. Diesel engines are lean burn engines.
Trucks
Diesel engines are widely common in large automobiles like truck,buses etc because it has more power then Gasoline engines. The Gasoline powered automobile are major exceptions like Diesel cars are less in number's worldwide.
Due to Diesel engine is a better substitution to large size inefficient steam powered engine because it is small as well as far more efficient it has replaced it in latter half of the 20th century, and is now used almost exclusively for the combustion engine of self powered rail vehicles (locomotive's and rail car's).
The first diesel-powered flight of a fixed-wing aircraft took place on the evening of 18 September 1928, at the Packard Proving Grounds near Utica, Michigan. With Captain Lionel M. Woolson and Walter Lees at the controls the first "official" test flight was taken the next morning, flying a Stinson SM1B (X7654), powered by a Packard DR-980 9-cylinder diesel radial engine, designed by Woolson. Charles Lindbergh flew the same aircraft and in 1929, it was flown 621 miles (999 km) nonstop from Detroit to Langley Field, near Norfolk, Virginia. In 1931, Walter Lees and Fredrick Brossy set the nonstop flight record flying a Bellanca powered by a Packard diesel for 84 hours and 32 minutes. X7654 is now owned by Greg Herrick and is at the Golden Wings Flying Museum near Minneapolis, Minnesota.
Diesel engines were produced in both Germany and United Kingdom by different companies with the production run of 900 engines Junker Jumo 205 was the most produced aviation Diesel engine of all times till now. In the Soviet Union Institute of TsIammade a significant progress in building of practical diesel aero-engines.
Military uses Diesel engine's because Diesel has lower risk of catching fire and it's engine's are much more powerful then other fuel's engine thus providing higher rate of torque and low rate of stalling.
Diesel powered cars have much more powerful engine's and better fuel efficiency although creating much more pollution then petrol or gasoline powered cars. Diesel powered cars are more expensive and take higher maintainence charges and more fuel efficient.

Military uses Diesel engine's because Diesel has lower risk of catching fire and it's engine's are much more powerful then other fuel's engine thus providing higher rate of torque and low rate of stalling.
Cars
Diesel powered cars have much more powerful engine's and better fuel efficiency although creating much more pollution then petrol or gasoline powered cars. Diesel powered cars are more expensive and take higher maintainence charges and more fuel efficient.
Tractors and heavy equipment
In modern day era most of the tractors and heavy equipements mostly diesel powered. Among the tractors only smaller classes have Gasoline or Petrol engine's.
Other uses
The Diesel engine's are used a lot equipment's and vehicle's which need's less flammabilityand higher fuel efficiency.
Pricing
The price of Diesel is less then Gasoline or Petrol especially in India otherwise it depends on country to country due to taxation and availability of resources that what price it should be.
