NEW GENERATION OF DIRECT INJECTION

Abstract

This paper describes direct fuel injection systems in the engine working space. Increasing the efficiency of SUS engines has always been a topic of constant research and improvement in order to maximize the thermodynamic potential, in order to bring the real cycle closer to ideal. The new concept of direct injection has achieved better formation, mixing, combustion and cooling of the mixture due to the entire injection and evaporation in the combustion chamber. The suscep­tibility to detonation combustion is reduced, as a result of which the degree of compression is increased. These and other factors affect the increase of engine output para­meters (power and torque) compared to conventional injection systems, while fuel consumption and exhaust emissions are reduced. The layered mixture characteristic of these engines is formed in three ways of conducting charge: wall, air and jet.
