Caterpillar announced new alcohol-based fuel conversion solutions for MaK engines. The dual-fuel conversion, for M 43 engines, is engineered to operate on up to 95% methanol or ethanol by volume which lowers greenhouse gas (GHG) emissions up to 80%.
The fuel-blending conversion allows operators to blend up to 35% methanol or ethanol with marine diesel oil (MDO), marine gas oil or biofuel equivalents to deliver GHG emissions reductions up to 20% for M 20 to VM 43 engines[i]. Both approaches support vessel owners’ sustainability initiatives and align with 2050 FuelEU Maritime Regulations.
Existing M 32 and M 43 engines are transformed into methanol and ethanol dual-fuel capable systems by the dual fuel conversion’s high-pressure direct injection (HPDI) technology. The fuel-blending solution is specifically engineered for diesel M 20 to VM 43 engines. This allows operators to seamlessly transition between methanol or ethanol and diesel, providing flexibility to support annual fleet-wide sustainability objectives. It also provides operators important fuel flexibility port to port while maintaining the engines’ inherent ability to run on biofuels.
Given the expense of permanently taking a vessel out of commission or building a new ship, the kits represent an economical alternative that enables operators to utilize
