Diesel engine means an engine which works on the compression-ignition principle.
Compression Ignition Engine means an internal combustion engine with operating characteristics significantly similar to the theoretical diesel combustion cycle. The regulation of power by controlling fuel supply in lieu of a throttle is indicative of a compression ignition engine.
Ultra Low Sulfur Diesel Fuel means diesel fuel that has a sulfur content of no more than fifteen parts per
Slow sand filtration means a process involving passage of raw water through a bed of sand at low velocity (generally less than 0.4 meters per hour (m/h)) resulting in substantial particulate removal by physical and biological mechanisms.
