A stratified exhaust gas re-circulation (EGR) engine uses an exhaust port per cylinder for exhausting exhaust gases and to re-circulate exhaust gas. The EGR valve may be phased from the exhaust stroke to the intake stroke. The EGR valves that control the exhaust gas re-circulation ports may be on a separate camshaft from the other valves. The EGR ports and an intake port for each of the cylinders may be helical or tangential ports that stratified the exhaust gas and the air in the cylinder. The engine may be a direct injection or a port fuel injection engine with one or more exhaust manifolds. The exhaust gas re-circulation ports may be controlled by a single flow valve or each port may have a separate flow valve. The intake ports may be controlled by a single flow valve or each intake port may have a separate flow valve.

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.

Minimizing fuel injector opening time greatly improves fuel efficiency and performance. Pre-charging the fuel injector solenoid is an inexpensive means of reducing opening time. The solenoid is pre-charged to a level that is slightly below a current level that would move an armature located near the solenoid for a known period. A larger current is then applied to the solenoid which moves the armature quickly to an open position. A current is then applied that is less than the pre-charging or valve-opening current to hold the armature in a open position. Finally, all current is removed from the solenoid, allowing the armature to return to a closed position.

A fuel injector nozzle assembly includes an injector body including a valve seat with a supply passage through which fuel flows generally along a supply axis. A nozzle plate having a top surface and a bottom surface is mounted onto the valve seat. The top surface includes a recess formed therein whereby fuel flows into the recess from the supply passage. A plurality of swirl chambers are formed within the top surface, each having a conical orifice extending from the swirl chamber to the bottom surface of the nozzle plate. A plurality of channels interconnect each of the swirl chambers to the recess, wherein the channels meet the swirl chambers offset from a center of the swirl chambers.

A fuel injector nozzle assembly includes an injector body including a valve seat with a supply passage through which fuel flows generally along a supply axis. The valve seat presents an upper surface which is adapted to engage a valve to seal the supply passage. A nozzle plate is mounted onto the valve seat and includes a plurality of orifice holes therein through which fuel flows. The valve seat further includes a first edge protrusion protruding into the fuel flow for generating a first separation of the fuel flow, thereby creating a plurality of small eddies which are entrained within the fuel flowing adjacent thereto. A turbulence cavity is defined by the nozzle plate and the valve seat wherein fuel flows into the turbulence cavity through the supply passage and out from the turbulence cavity through the plurality of orifice holes.
