The phrase "advanced injection timing" is correct and usable in written English.
It can be used in contexts related to automotive engineering or performance tuning, specifically when discussing the timing of fuel injection in engines.
Example: "The mechanic recommended adjusting the advanced injection timing to improve the engine's performance and fuel efficiency."
Alternatives: "enhanced fuel injection timing" or "optimized injection timing".
The fuel spray model simulates the injection process, the fuel-air mixture formation, the in-cylinder gas mixture evolution and accounts for the fuel-wall impingement that usually occurs in case of low-medium injection pressure or advanced injection timing.
The experimental measurements have been carried out at the engine test stand, investigating operating conditions with highly advanced injection timing and low rail pressure, in order to induce the fuel impingement process.
The BSFC decreased but the NOx emission increased with advanced injection timing under dual-fuel operating conditions.
Ignition delay (ID), as well as combustion duration decreased with advanced injection timing, injector opening pressure (IOP) and the compression ratio (CR), while the peak pressure and heat release rate (HRR) increased.
The response surface analysis indicates that increasing the compression ratio with advanced injection timing and low CNG flow rate help to improve the performance of DF engine fueled with HOME and CNG in terms of the increased brake thermal efficiency (BTE) and reduced emissions (Smoke, Carbon monoxide, Hydrocarbon) except the oxides of nitrogen (NOx) emissions.
However, retarded injection timing caused effects in the other way.
It has been observed that advance in injection timing from factory settings caused reduction in BSFC, CO, HC and smoke levels and increase in BTE, Pmax, HRRmax and NO emission with Jatropha biodiesel operation.
The same feature was observed in diesel engine operation using ordinary diesel fuel with advanced ignition timing to make ignition occur after the end of fuel injection.
The optimal injection timing was more advanced with lower load and higher NSC conditions.
Use of the stepped bowl allowed injection timing to be advanced at full load, a condition constrained, in this work, by strict limits of cylinder pressure and exhaust temperature.
The experimental data show that the advances in the start of injection timing, using biodiesel rather than mineral diesel, are smaller than those calculated with standard methods and may even not occur at all, depending on injection system design.
