Embodiment Construction

[0023] The present invention relates to compensating for the combustion of fuels having different cetane numbers. figure 1 shows an example of a supercharged diesel engine in which Figure 7-8 A method to adjust fuel injection to improve engine emissions and / or reduce combustion noise. Figure 2-6 An example of simulating fuel injection timing to compensate for burning fuels with different cetane numbers is shown.

[0024] refer to figure 1 , an internal combustion engine 10 comprising a plurality of cylinders— figure 1 One of the cylinders is shown - controlled by the electronic engine controller 12 . Engine 10 includes combustion chamber 30 and cylinder walls 32 with piston 36 disposed therein and connected to crankshaft 40 . Combustion chamber 30 is shown communicating with intake manifold 44 and exhaust manifold 48 via respective intake valve 52 and exhaust valve 54 . The intake and exhaust valves may each be operated by an intake cam 51 and an exhaust cam 53 . The p...

Abstract

The invention discloses a method and a system used for adjusting fuel injections provided to a cylinder during a cyclying period of the cylinder. In one example, the amount of fuel is moved among the fuel injections in response to a combustion phase. If cetan of the combusted fuel is changed, hydrocarbon and / or particles containing carbon into the engine can be reduced.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of U.S. Patent Application Serial No. 13 / 291,852, entitled "Method for Controlling Low Temperature Combustion," filed November 8, 2011, which was filed on October 8, 2010 US Patent Application No. 12 / 900,959, entitled "Method for Controlling Low-Temperature Combustion," filed on , is now a continuation of US Patent No. 8,051,829, the entire contents of which are hereby incorporated by reference for all purposes. technical field Background technique [0003] Diesel fuel can be supplied to customers in different properties at different times of the year. For example, additives can be mixed with diesel fuel to improve combustion during cold or warm weather. Also, different fuel refiners can process diesel fuel in slightly different ways, so the properties of diesel fuel can vary slightly between different dispensers. One property that can vary from season to season and from dis...
