Engine replacement or Ã¢ÂÂre-poweringÃ¢ÂÂ is the replacement of an older diesel engine with a new, low emission engine system.
Ã¢ÂÂUpgradingÃ¢ÂÂ means the addition of emission reduction components, often during an engine rebuild. Emission upgrade kits can often be fitted at the time of a rebuild which is a fairly low cost option to improve the emission performance, improve fuel economy, reduce maintenance costs and extend an engines life.
Emission reduction benefits will depend on the originally certified emission level of the vehicle and the replacement engine used. Average emissions reductions vary from 25 up to 75%
