TL;DR: In this article, the spray characteristics of an air-assisted injector under various injection parameters and ambient conditions were investigated in a constant volume chamber experimentally, where high-speed backlight imaging technique was used for spray visualization to obtain macroscopic characteristics such as spray shape while Phase Doppler Particle Analyzer was utilized to measure spray droplet diameter and velocity.

TL;DR: In this article, the dilution, thermal and chemical effects of IMWI on the combustion and emissions characteristics of a four-stroke, direct injection as well as turbocharged diesel engine are investigated by CFD simulation.

TL;DR: In this article, a prototype of a hydraulic free piston engine has been developed to achieve efficient energy conversion directly from chemical energy of fuel to hydraulic energy, and the experimental results show that the majority of fuel burns in the rapid combustion phase due to the high piston velocity in the final part of the compression stroke.

TL;DR: In this paper, the performance characteristics of a multilayer thermoelectric generator are investigated for the exhaust heat recovery of a heavy-duty diesel engine, and the potential for the power output is estimated based on the world harmonised transient cycle.
