Internal Combustion Engine / Emergency Generator

Regulations and applications for industrial diesel generators and engines.

Compression Ignition (Diesel) Engines

If you intend to install a diesel engine (also known as a compression ignition internal combustion engine) and this engine was ordered after July 11, 2005, and manufactured after April 1, 2006, and is not a fire pump engine, then the engine is subject to federal New Source Performance Standards (NSPS) found under 40 CFR 60 Subpart IIII.

This federal NSPS also applies to diesel engines that are modified or reconstructed after July 11, 2005. For fire pump engines, the federal NSPS applies to engines ordered after July 1, 2006 that are manufactured as a certified National Fire Protection Association (NFPA) fire pump engine.
