The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure. The control pressure is ...
This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions.
The dual-fuel 235 hp (175 kW; 238 PS) LW2 version was able to run on petrol and autogas. The LW2 engine was based on the low-output LE0 V6. It featured a factory-fitted dual-fuel system developed by IMPCO, different valves, and hardened titanium valve seats. This motor was available exclusively in Holden vehicles from 2005–2012. Applications: [7]
In a common-rail system, fuel from the fuel tank is supplied to a common header (called the accumulator), and then sent through tubing to the injectors, which inject it into the combustion chambers. The accumulator has a high-pressure relief valve to maintain pressure and return the excess fuel to the fuel tank.
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

A low-pressure injector then sprays fuel into the combustion chamber, where it vaporizes as it mixes with the compressed air. A high-pressure GDI system was developed by German company Ficht GmbH in the 1990s and introduced for marine engines by Outboard Marine Corporation (OMC) in 1997, in order to meet stricter emissions regulations. However ...
Fuel delivered via higher-pressure pump, fuel rails, distribution lines and all-new, seven-hole fuel injectors; Fuel injectors spray directly onto glow plugs, providing faster, better-quality starts and more complete cold-start combustion for reduced emissions; Improved glow plugs heat up faster through an independent controller
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
