MAN Engines, a pioneer in low-emission engines for harbour craft, has become the first engine manufacturer to offer certified V12 engines for medium- and heavy-duty applications complying with the highest level of Commercial Harbour Craft (CHC) requirements as set by the Californian Air Resources Board (CARB) in the US.
Since the CARB CHC Regulation came into force early in 2023, engines must be equipped with certified diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems to be granted the necessary approvals. MAN Engines relies on a fully integrated exhaust gas aftertreatment system that coordinates the engine, DPF, and SCR systems to ensure compliance.
Werner Kübler, head of Engineering at MAN Engines, said: “Our customers receive a system completely from a single source. That's why the engine, diesel particulate filter and SCR system are perfectly matched to each other.”
The Environmental Protection Agency (EPA) Tier 4 engines that meet the standard are four variants of the 12-cylinder MAN D2862 unit including 1,000-hp, 1,200-hp, 1,250-hp, and 1,450-hp engines.
