A logical sensor method is provided for internal combustion engines (Compression Ignited or Spark Ignited) based on a software algorithm (SBS). This algorithm identifies the mixture diesel/bio-diesel present in a vehicle's fuel tank and adapts the engine control strategy as a function of the fraction of FAME (Fatty Acid Methyl Esters) vegetal-based oil or oil produced from organic waste blended into a crude oil based diesel fuel (average chemical formula CH).

SBS logical bio-diesel sensor

A fuel injector for spraying fuel into a combustion chamber comprises a spray head () extending along a central axis (X) from a base () to a free end (), the head comprising a free outside face () defining an internal injection combustion (), and at least two groups () of injection orifices, each of the groups () of injection orifices comprising a first orifice () and at least one second orifice (), each adapted to spray a fuel jet along a respective first and second directions (D, D, D; D, D, D), the first and second directions forming between them an acute angle (&#x3b1;). All of the internal openings of the injection orifices in each of the groups of orifices are situated substantially in a common plane (P) extending substantially transversely relative to the central axis (X) of the head () of the injector. The injector particularly intended for a direct-injection diesel engine.

Fuel injector and an engine including such as injector

The invention concerns a relief device for a high-pressure direct-injection pump supplying petrol to an automobile vehicle engine injector manifold, the pump being supplied with fuel by a low-pressure electric fuel pump communicating with a fuel tank and the high pressure delivered being regulated by a pressure regulator, said pressure regulator taking the form of a three-way valve supplying fuel to the manifold via the fuel pump below a predetermined engine rotation speed threshold and then supplying the manifold via the top part of the injection pump when the engine speed is above the predetermined threshold.
