The advancement of highly boosted internal combustion engines (ICEs) with high thermal efficiency is mainly constrained by knock and super-knock, respectively, due to the end gas autoignition detonation development. pressure wave propagation reflection in a small confined space may strongly interact local autoignition, leading characteristics different from those large chamber or open space. pr...

The expected increase in the use of environmentally friendly liquid fuels medium and heavy-duty compression ignition engines (for both off-road transport applications), together with well-documented benefits hydrogen-carriers to decrease energy dependence achieve a neutral-carbon economy (internal combustion highly contributing global CO2 emissions), have motivated this work. autoignition chara...

The condition of the natural environment, including breathable air, indicates that actions are to be taken related reduction exhaust emissions from transport. One sectors transport is aviation. tightly types fuels in this sector In paper, authors propose application a new generation jet fuels. A full exploration physicochemical properties these requires research under actual engine operation. c...

Gasoline compression ignition (GCI) has been shown as one of the advanced combustion concepts that could potentially provide a pathway to achieve cleaner and more efficient combustion engines. Fuel and air in GCI are not fully premixed compared to homogeneous charge compression ignition (HCCI), which is a completely kinetic-controlled combustion system. Therefore, the combustion phasing can be ...

Numerical simulations have been carried out for spontaneous ignition of pressurized hydrogen release directly into air. Results showed a possible mechanism for spontaneous ignition due to molecular diffusion. To accurately calculate the molecular transport of species, momentum and energy in a multi-component gaseous mixture, a mixture-averaged multi-component approach was employed in which ther...

There is growing interest in using biodiesel in place of or in blends with petrodiesel in diesel engines; however, biodiesel oxidation chemistry is complicated to directly model and existing surrogate kinetic models are very large, making them computationally expensive. The present study describes a method for predicting the ignition behavior of blends of n-heptane and methyl butanoate, fuels w...
