    A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power.. Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine's crankshaft. The turbocharged, turbocompounded, direct-injection stratified charge Wankel rotary combustion engine is the most promising future powerplant of general aviation. Its advantages include high power density, multi-fuel capability, no balancing problems due to lack of reciprocating parts and low NO emissions. The problem which has.

The stratified charge range of an engine with gasoline direct injection and spray-guided combustion system is shown in Fig. The fuel consumption of the engine is favourable when operated using a lean mixture throughout a wide load and engine speed range. The best point shows an effective specific consumption of approximately g/ by: 3.

Scheme of charge propagation. Using the CAD program a mode of charge stratification of ultra – lean combustion was elaborated based on considering the shape of the concave bowl of the piston and injection castor angle presented in Fig The small spheric bowl in the piston shown in Fig.1 works as a chamber and is located on the side of the inlet by: 4.

A stratified charge engine describes a certain type of internal combustion engine, usually spark ignition (SI) engine that can be used in trucks, automobiles, portable and stationary term "stratified charge" refers to the working fluids and fuel vapors entering the cylinder.

Usually the fuel is injected into the cylinder or enters as a fuel rich vapor where a. The rotary engine of the Wankel type is currently undergoing a renaissance in the combustion engine industry, mainly because of the simplicity of its design and high power to weight ratio.

Strong reliability increases the demand in the aero industry where it is used mainly in small aircrafts such as drones. In the engine development process, there is a high demand for 1 Author: Milan Drbal, David Svida.

An internal-combustion engine with a divided ignition cylinder that uses the ignition of rich fuel in a small chamber near the spark plug. engine The principle of stratified charge applies to direct injection petrol engines.

It involves concentrating spraying of the fuel close to the spark plug rather than throughout the whole of the combustion chamber. This method of operation delivers a reduction in fuel consumptionthat can reach 40% when the engine is running at very low charge.

>File Size: 80KB. The diesel engine (also known as a compression-ignition or CI 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 (adiabatic compression).This contrasts with spark-ignition engines such as a petrol engine (gasoline.

Fuel Stratified Injection or FSI is a proprietary direct fuel injection system developed and used by Volkswagen AG, as well as its luxury subsidiary Audi. It was first introduced in when VW introduced the litre direct-injected inline-four unit in the Volkswagen Lupo city car. The system was adapted from Audi's Le Mans prototype race car R8 and has since proliferated throughout .This important book, in two volumes, reviews the science and technology of different types of DI combustion engines and their fuels.
