Diesels are more reliable. Diesels run cooler. Because they are more efficient, diesel engines release less waste heat while in operation. Diesels last longer. Diesel engine parts are generally stronger than gas engine components, and diesel fuel has superior lubricating properties.
As a result, diesel engines tend to last twice as long as gas- powered ones. Diesel fuel is safer. Diesels are more easily turbo-charged. Diesels produce minimal carbon monoxide. Diesel engines, because they have much higher compression ratios for a typical diesel vs. Diesel engines also more expensive. Diesel engines, because of the weight and compression ratio, tend to have lower maximum RPM ranges than gasoline engines.
This makes diesel engines high torque rather than high horsepower, and that tends to make diesel cars slow in terms of acceleration. Diesel engines must be fuel injected, and in the past fuel injection was expensive and less reliable 6. Diesel engines tend to produce more smoke and "smell funny". Diesel engines are harder to start in cold weather, and if they contain glow plugs, diesel engines can require you to wait before starting the engine so the glow plugs can heat up.
Diesel engines are much noisier and tend to vibrate. Diesel fuel is less readily available than gasoline You just clipped your first slide!

The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. Diesel engines are used in aircraft , automobiles , power generation , diesel-electric locomotives , and both surface ships and submarines. This is an idealized mathematical model: real physical diesels do have an increase in pressure during this period, but it is less pronounced than in the Otto cycle. In contrast, the idealized Otto cycle of a gasoline engine approximates a constant volume process during that phase.
Stratified charge engine
Diesel engine , any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder , where combustion and expansion actuate a piston. It converts the chemical energy stored in the fuel into mechanical energy , which can be used to power freight trucks, large tractors, locomotives, and marine vessels. A limited number of automobiles also are diesel-powered, as are some electric-power generator sets. The diesel engine is an intermittent-combustion piston-cylinder device.
One of the confusions prevailing among the car buyers is the difference between the petrol gasoline engine and the diesel engine. Perhaps the common knowledge or perception is that the diesel motors are noisier and their vibration is intolerable, whereas petrol motors run smoothly. Well this is not far from the truth though. But, with the modern engine technology, diesel engines are more competitive than before, so we have cars running efficiently, and we also have an increasing popularity and demand. Petrol and diesel engines are the most popular internal combustion engines used predominantly in modern vehicles, with the diesel also heavily used in construction industry to manage heavy loads. We will unfold the differences between these engines. How do gasoline and diesel engines work?
Diesel is an increasingly popular fuel in European cars, with over half of new registrations of this type. What are the differences between these two propellants? Conventional diesel and petrol are both produced from mineral oil, but the precise refining methods vary.
The diesel and petrol engines that are used in most cars are highly similar. In essence, they are internal combustion engines that work using a two or four-stroke cycle. In an internal combustion engine, the power cycle is made up of four phases: intake, compression, power and exhaust.
The diesel engine , named after Rudolf Diesel , is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression; thus, the diesel engine is a so-called compression-ignition engine CI engine. This contrasts with engines using spark plug -ignition of the air-fuel mixture, such as a petrol engine gasoline engine or a gas engine using a gaseous fuel like natural gas or liquefied petroleum gas. Diesel engines work by compressing only the air.
