Recently, large market of industrial machinery is formed across Asian countries due to the mechanization of industries. In China and India, where further economic growth is expected, tighter exhaust emissions regulations are phased in for industrial diesel engines with the rise of environmental awareness. On the other hand, high durability, low fuel consumption and low cost are earnestly requested for those engines. While diesel engines with mechanical direct fuel injection system have potential to meet their demands at high levels, it is difficult to achieve both low-fuel consumption and low-exhaust emissions.  To exhibit these performances, it is important to keep good condition of combustion even under high EGR rate. We adopted high pressure fuel supply pump, and concave fuel cam profile which realize high injection rate for promoting atomization of injected fuel.

The injection amount per stage in the multiple injection strategy is smaller than the conventional single-stage injection. The research of the spray mixture formation and the combustion characteristics with a small injection amount is being meaningful. In this study, the effect of the injection amount (0.27mg, 0.89mg, 2.97mg) under 100MPa injection pressure and the effect of injection pressure (100MPa, 170MPa) under different injection amount (0.27mg, 2.97mg) on the spray and mixture formation characteristics were studied based on the vapor and liquid phase concentration distributions in the fuel spray by using the tracer LAS technique. In order to satisfy the requirements for the LAS test fuel, the tracer LAS technique was adopted. The spray was injected used a single-hole nozzle with a diameter 0.133mm into the high-pressure and high-temperature constant volume vessel.

The aim of this investigation was to improve understanding and quantify the impact of exhaust gas recirculation (EGR) as an emissions control measure onto cyclic variability of a small-bore, single-cylinder, diesel-fueled compression-ignition (CI) power generation unit. Of special interest were how cycle-to-cycle variations of the CI engine affect steady-state voltage deviations and frequency bandwidths. Furthermore, the study strived to elucidate the impact of EGR addition onto combustion parameters, as well as gaseous and particle phase emissions along with fuel consumption. The power generation unit was operated over five discrete steady-state test modes, representative of nominal 0, 25, 50, 75, and 100% engine load (i.e. 0-484kPa BMEP), by absorbing electrical power via a resistive load bank. The engine was equipped with a passive EGR system that directly connected the exhaust and intake runners through a 4mm diameter passage.

Non-volatile particle number distributions from a single cylinder industrial diesel engine were measured at several operating conditions spanning the torque curve. The effect of increasing the air-fuel ratio by injecting compressed shop air at various boost pressures was also investigated. A bi-modal distribution separated at approximately 20 nm was observed for most operating conditions. Depending on operating condition, the engine produced between 1014 to 1015 particles per kW-hr. Energy specific particle number emissions (per kW-hr) were seen to be strongly dependent on speed and load. Minimum emissions occurred at intermediate speeds and loads. Particles below 20 nm increased with increasing air-fuel ratio, while the opposite trend was observed for particles greater than 20 nm. Variation in total particle surface and total particle volume followed the same trends as the particles from the larger mode.
