Abstract
A low pressure direct injection engine system for a vehicle includes an engine having a plurality of cylinders each including a piston wherein the cylinders and a top portion of the pistons define a plurality of combustion chambers. A fuel injector is mounted in fluid communication with each of the combustion chambers. Each fuel injector has a nozzle which is adapted to generate a fine fuel spray with droplet sizes of 25 micro-meters SMD and 45 micro-meters DV90 and low penetration at fuel pressure of roughly 2 MPa. A low pressure fuel delivery system is adapted to deliver fuel from a fuel tank within the vehicle to the fuel injectors, and an igniter is mounted within the combustion chamber which is adapted to ignite the fuel within the combustion chamber.
