Experiences of Heavy-Duty Alcohol-Fuelled Diesel-Ignition Engines

The paper presents the development and experiences of the multifuel TM101G engine. The standard TD101G engine, which is a turbocharged, direct injection engine with a displacement of 9.6 litres, was modified and equipped with two separate injection systems. Diesel fuel was used to ignite the alcohol.

Performance and endurance tests were carried out, together with emission measurements. Twenty trucks and buses run on methanol or ethanol were involved in a field test. Fuel consumption and oil analyses were followed up.
