what is the difference between common rail diesel and direct injection?
157703
A common rail is one of the most important components in a diesel and gasoline direct injection system. The main difference between a direct and a standard injection is the delivery of fuel and the way how this one mixes with incoming air. ... The common rail is a long metal cylinder.

GDI engines provide many benefits that conventional fuel injection can't. With gasoline direct injection technology, you can draw more power from smaller engines. In addition, your car gets improved fuel efficiency and reduced emissions. While great, the power of the GDI engine is a double-edged sword.

Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber.

Financial: diesel engines are more efficient and use 15−20% less fuel meaning cheaper running costs. ... For newer diesel cars though, tax is typically higher than for petrol. Driving experience: diesel cars offer more low-speed torque which means they have better overtaking power and towing ability.

While new generation diesels emit lower levels of carbon dioxide than petrol engines, they tend to emit higher levels of NOx. In built-up urban areas, these emissions mean that diesel engines are often the biggest cause of roadside air pollution, particular among older models.

A CRDI abbreviation stands for Common Rail Direct Injection and is used by Hyundai Motor Group for their proprietary diesel engines with Common Rail direct fuel injection. CRDI engines are turbocharged power units installed on Hyundai and Kia vehicles.

Diesel–electric transmission is used on railways by diesel electric locomotives and diesel electric multiple units, as electric motors are able to supply full torque at 0 RPM. Diesel–electric systems are also used in marine transport, including submarines, and on some land vehicles.

Ryco have just released the Z699 fuel filter for Common Rail diesel applications. With a similar external design as the Z252X, the Z699 has a much high efficiency filter media inside with a nominal rating of 5 micron.

Direct fuel injection sprays fuel directly into the combustion chamber, while ported fuel injection sprays the intake manifold outside the valve. ... Throttle body fuel injection, while similar to a carburetor, has a separate throttle body with one fuel injector rather than fuel injectors located in each cylinder.

JCB DIESELMAX DIESELMAX engines are supplied with mechanical governing up from 63kW to 85KW and common rail electronic governing from 97KW to 120kW. For Power Generation applications the range meets the European Stage 3 emissions limits.

A premium diesel has a higher cetane number, better lubricity and includes detergents that provide injector-cleaning capability versus standard #2 diesel. Cetane measures a fuel's ignition delay. ... Detergents keep fuel injectors clean for optimal engine performance.

Generally less easily. Diesel vehicles naturally have more toque than petrol engines do. This therefore means that they are less likely to stall when taking off at the lights etc than a petrol engine. Petrol engines though can naturally take off faster than diesels though.

With GDI engines, a common fuel line injects gasoline at high pressure directly into the combustion chamber of each cylinder. ... Because GDI engines directly inject gas into the cylinder, small amounts of dirt from intake air and blowback carbon build up on intake walls.

Indirect injection. Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. ... Direct injection allows the fuel to be precisely metered into the combustion chamber under high pressure which can lead to greater power, fuel efficiency.

2 diesel fuel oil are almost the same thing (diesel is different in that it also has a cetane number limit which describes the ignition quality of the fuel). Distillate fuel oils are distilled from crude oil.

Direct injection improves combustion efficiency, increases fuel economy and lowers emissions. ... Both systems use electronic fuel injectors to spray fuel into the engine, but the difference is where they spray the fuel. With port injection systems, fuel is sprayed into the intake ports.

Their primary differences are their wet & dry boiling points and their composition. DOT 3 is the most common type used in cars and trucks today. DOT 4, however, is gaining popularity due to widespread use of anti-lock braking systems and traction control, which benefit from DOT 4 fluid's lower viscosity.
