New strategies for control and feeding of air/fuel homogenous mix for internal combustion engines, mainly for fuel injection engines. This new strategies are to get an air/fuel mixture homogeneous and of adequate volume. Fuel in contact with air for a sufficient length of time required for ...
vapor pressure and swirl ratio on emissions and performance of the DME engine must be critically evaluated and compared with those of diesel engine. The present chapter focuses on adopting suitable changes in fuel injection strategies to enhance the emission and performance characteristics of DMEs fue...
摘要: PROBLEM TO BE SOLVED: To improve NOX purification rate by providing a fuel injection controller which can maintain the temperature of a lean NOX catalyst fitted in an exhaust system to an optimum temperature without using auxiliary injection....
Novel Fuel Injection Strategies for PCCI Operation of a Heavy-Duty Turbocharged Diesel EngineTowards the objective of achieving benefits of the Premixed Charge Compression Ignition (PCCI) mode in a multi-cylinder, turbocharged, common-rail, direct injection, heavy-duty die... 查看全部>>...
However, to take advantage of DFI, it is necessary to operate in multiple control modes. One of the DFI control strategies is set for very low required engine power including idle and some constant engine load conditions at low-to-moderate vehicle speeds. Another control strategy would be ...
On the contrary, the modulation of the injection rate showed to be ineffective at medium engine load, since the increase in soot was greater than the relative decrease in NOx. The analysis of the modifications produced by these strategies on the combustion process, and on the rate of heat ...
A fuel injection control system for a diesel engine configured to perform multiple fuel injections to induce multiple combustions. A PCM 70 is configured to, during compression stroke, perform a main injection and multiple pre-stage inje... S Naotoshi,M Tsunehiro,I Kiyoaki,... 被引量: 0发表...
increased the energy efficiency of a gasoline direct injection engine through optimizing the synchronization strategies of the fuel injection.13 They make the mixture characteristics properly adapted to the specific working condition in order to increase the engine energy efficiency. Loop-up table is ...
The control strategies of auto-ignition for homogeneous charge compression ignition and controlled auto-ignition operations were investigated using a simple engine model. The fluctuations of auto-ignition characteristics during transients in variable timing of exhaust and intake valves were analyzed. When th...
This paper is the delineation of the computational and test strategies for another injector nozzle for a consecutive dual fuel engine. The goal of this rev... MADP Patel Nimit - 《International Journal of Theoretical & Applied Mechanics》 被引量: 0发表: 2017年 Behavior of Fuel Spray Injected...
