GASOLINE DIRECT INJECTION.

PRESENTED BY: GUIDED BY: PRAVEEN RAJ BV V. S8MB ASSOCIATE PROF. NSSCE DEPT. OF MECH. NSSCE INTRODUCTION. In internal combustion engines, gasoline direct injection (GDI), is a variant of fuel injection employed in modern two-stroke and four-stroke gasoline engines.

Direct injection methods: There are two ways of direct injection 1) direct injection of liquid fuel and 2) direct injection of premixture injection. Direct injection of liquid fuel: it is a high pressure fuel injection system in which liquid fuel is directly injected into the engine cylinder.

Direct fuel injection was used in notable World War II airplane engines such as the Junkers Jumothe Daimler-Benz DBthe BMWthe Shvetsov AShFN (MFN). German direct injection petrol engines used injection systems developed by Bosch from their diesel injection systems.

Abstract. The inhomogeneous mixture formation of spark-ignition engines with direct injection (DISI engines) as well as the significantly different flow field conditions compared to multi-point fuel injection (MPFI) engines pose severe new challenges in understanding the combustion process.

Gasoline Direct Injection is starting to take over and the development has gone forward. Car makers from Ford, Chevy, Honda, Mazda and much more have adopted this technology. Until now, however, no one has successfully designed an in-cylinder direct injection engine for use on production vehicles.

A result of Mitsubishis engine development capabilities, Mitsubishis advanced Gasoline Direct Injection GDI engine is the realization of engineering dream. Mitsubishi Gasoline Direct Injection GDI Engine. A single cylinder diesel engine that is equipped with a manual direct injection system is considered for the experimental work.

vehicle manufacturers are increasingly turning to gasoline direct injection (GDI) coupled with. turbocharging as a cost-effective option for improving the efficiency and performance of gasoline engines. While GDI engines are expected to account for 60% of the U.S.

market byand the technology offers fuel economy and CO. reduction. Combination direct injection and port injection in one engine. That seems to be the solution for the valve buildup issue from direct injection only engines. I had heard a while back that Toyota was testing this technology and I believe has started.

Direct-injection technology is designed to squeeze more mpg out of cars. It has actually been delivering results, but the technology can lead to more time in the repair shop. Consumer Reports. The main difference between Carburetor and Fuel injection system {CarburetorzFuel is atomized by processes relying on the air speed greater than fuel speed at the fuel nozzle, zThe amount of fuel drawn into the engine depends upon the air velocity in the venturi {Fuel Injection SystemzThe fuel speed at the point of delivery is greater than the air speed to atomize the fuel.

pressurized fuel to flow from the fuel supply line, through the open injector, into the engine. Fig Schematic Diagram of Direct Gasoline Fuel Injection System for a Two Stroke SI Engine The fuel injector is an electro-mechanical device which meters, atomizes and directly supplies fuel into the cylinder based on signals from the controller.

Direct injection works well with other engine technologies Automakers are finding all sorts of new ways to further refine the internal combustion engine with the aid of direct injection technology.

Before we look inside the direct injection engine, let's view a quick second in the life of a standard gasoline engine (for a more complete look at the gasoline engine, check out How Car Engines Work).First, the fuel travels via pump from the fuel tank, through the fuel line and into fuel injectors that are mounted into the engine.

Diesel engines have long used direct injection, but it is only in the past few years that manufacturers have adopted it for widespread use in gasoline or petrol engines, as it is called in Europe.

Weight of the engines: In CI engines the compression ratio is higher, which produces high pressures inside the engine. Hence CI engines are heavier than SI engines. Speed achieved by the engine: Petrol or SI engines are lightweight, and the fuel is homogeneously burned, hence achieving very high speeds.

CI engines are heavier and the fuel is. Fuel injection systems (gasoline) Ricardo Pimenta Fábio Daniel The fuel delivery system is responsible for fuel delivering at the engine. The system is composed by the fuel tank, the pipes, one or more fuel filters, a fuel pump that could be mechanical or electric and the fuel Direct Injection Fuel delivery system.

Multiple fuel injection, which includes the early injection in the intake stroke is able to decrease the temperature of the hot spots and makes the combustion phasing at knocking limit advanced by 2 [] without increasing the smoke emission. Direct injection engines are nothing new for diesel lovers.

The application of direct injection in gasoline engines in large volume is a much newer feat however. As far back asmanufacturers have tried to inject gasoline directly into the cylinder, companies such as: Mercedes, Ford, AMC and many others all tried to perfect the technology. The TSI engine combines direct injection with turbocharging and in some cases even twincharging, as the some performance-oriented TSI engines are.

Gasoline Direct Injection Boosted Engine Systems • Gasoline Direct Injection is a Key Enabler to Improve Low end Torque in Boosted Engines - Improved Volumetric Efficiency - Direct injection with cam phasing allows scavenging with fresh air to reduce residual gas fraction - Reduced knock propensity - In-cylinder fuel vaporization reduces.
