The injection and spray characteristics of diesel and gasoline blends are investigated on a common rail injection system. The injection rate, fuel spray evolution process (tip penetration distance, spray cone angle, projected spray area and relative brightness intensity contour) and microscopic...

This paper deals with a class of backward stochastic differential equations (BSDEs in short). Under a kind of non-Lipschitz assumptions, the authors obtain the existence and uniqueness of solution to BSDE.

Though, as a renewable energy resource, alcohol fuel has many advantages in China, it is difficult for diesel engines to operate on alcohol due to its low cetane number and high latent heat of vaporization. This paper proposes an approach to its ignition problem by combining internal exhaust gas...

With life cycle assessment (LCA) methodology, a life cycle model of coal-based dimethyl ether (CBDME) as a vehicle fuel is established for China. Its life cycle from well to wheel are divided into three phases. They are feedstock extraction, fuel production and fuel consumption in vehicle. The...

Because the energy crisis and environmental pollution are significant concern, a next-generation combustion mode for internal combustion engines that can simultaneously reduce exhaust emissions and substantially improve thermal efficiency has attracted increasing attention. In the last two...

A mathematical model of a free piston linear engine is established. The motion characteristics as well as the natural frequency map of the free piston are established. Then, its motion characteristics are successfully explained from the oscillation point. The full simulation model is built up in...

A diesel engine is modified for homogeneous charge compression ignition (HCCI) combustion with dimethyl ether. With and without knock, in-cylinder pressure is acquired, and in-cylinder temperature, rate of heat release (ROHR), pressure rise rate and pressure rise acceleration obtained. Wavelet...

Biomass gasification using lattice oxygen (BGLO) of natural hematite coupling with steam was conducted in a fluidized bed reactor. The presence of hematite particles evidently facilitated to biomass gasification. Comparing with biomass steam gasification (BSG), carbon conversion and gas yield...

This study theoretically proposes and experimentally demonstrates the simultaneous reductions of NOx and soot using a novel combustion mode, (dual-fuel sequential combustion) DFSC, on a single-cylinder engine. DFSC introduces a well-mixed, lean fuel/air mixture into the cylinder by injecting...
