The Sulzer AL20/24 was introduced in 1960s as a medium-speed diesel engine that was meant to meet the gradually increasing demand for compact high energy engines in the growing shipping market. The AL20/24 engine found widespread use on vessels such as tugs, fishing boats, tankers and cargo vessels. Featuring a 200 mm bore with a 240 mm stroke, the AL20/24 engine produced power of about 130 kW to 145 kW per cylinder, at speeds between 700 rpm to 1,200 rpm. The AL20/24 engines were able to run on MDO and HFO, making them fuel flexible, and were renowned fro their long service life. They also paved the way for future engine series such as the A25 series. 

Though AL20/24 engines are now considered legacy engines, support for them still remains readily available through Sulzer specialists, OEMs and independent engine parts suppliers. With access to original unused surplus components sourced from decommissioned vessels and reliable sourcing through trusted local traders, Alang Maritime is a dependable option for Sulzer AL20/24 engine spare parts and maintenance requirements.
