Fuel injection in diesel engines [edit] Mechanical and electronic injection Older engines make use of a mechanical fuel pump and valve assembly which is driven by the engine crankshaft‚ usually via the timing belt or chain. These engines use simple injectors which are basically very precise spring-loaded valves which will open and close at a specific fuel pressure. The pump assembly consists of a pump which pressurizes the fuel‚ and a disc-shaped valve which rotates at half crankshaft speed

carbon. Thus‚ p-Nitroaniline can be prepared by means of electrophilic aromatic substitution. To begin‚ nitric acid needs to be activated as it has little electrophilic power. Thus‚ concentrated sulfuric acid is added to protonate the nitric acid. Dehydration produces the nitronium ion‚ which is a strong electrophile and has most of its positive charge on the nitrogen atom. The nitronium ion‚ acting as the electrophile in the nitration reaction‚ will attack the benzene ring and produces the nitrobenzene
