When too much steam is added, a condition known as " over steaming " can occur resulting in reduced combustion efficiency and higher emissions.
22.
When starting from cold, the engine's combustion efficiency is reduced because the cold engine block draws heat out of the cylinder in the compression stroke.
23.
This 12 Valve mode results in swirl of the intake charge which increases combustion efficiency, resulting in improved low end torque and better fuel economy.
24.
Many early rockets had burned kerosene, but as burn times, combustion efficiencies, and combustion-chamber pressures grew, and as engine masses shrank, the engine temperatures became unmanageable.
25.
The 2.2-litre, 4-cylinder engine features a pent-roof combustion chamber configuration and reduced friction loss from moving parts, which results in excellent combustion efficiency and low fuel consumption.
26.
Vehicle emissions are worsened by fuel adulteration and poor fuel combustion efficiencies from traffic congestion and low density of quality, high speed road network per 1000 people.
27.
Simultaneously, an oil jet sprays oil onto the underside of the piston to keep the engine in optimum operating temperature, hence delivering improved combustion efficiency and engine durability.
28.
Gas boilers can be designed for turndown ratios of 10-12 with little to no loss in combustion efficiency, while some gas burners may achieve a ratio of 35.
29.
The 2 . 2-litre, 4-cylinder engine features a pent-roof combustion chamber configuration and reduced friction loss from moving parts, which results in excellent combustion efficiency and low fuel consumption.
30.
The earliest VTEC-E implementation is a variation of SOHC VTEC which is used to increase combustion efficiency at low RPM while maintaining the mid range performance of non-vtec engines.
