Abstract

A Caterpillar 3406 turbocharged diesel engine was converted to operate in a natural gas with diesel pilot ignition mode and was evaluated for performance and emission characteristics for both diesel and natural gas operation. Full-load power was achieved with natural gas fueling without knock. Similar fuel efficiencies were obtained with natural gas fueling at high loads, but efficiencies were lower for low loads. Bosch smoke numbers were reduced by over 50 percent with natural gas fueling for all cases investigated. NOx emissions were found to be lower at low loads and at high speeds under high load. CO emissions were significantly increased for natural gas fueling while CO2 concentrations in the exhaust were reduced for natural gas fueling.
