日本松井铁工厂研究和发展了中型船用柴油机油冷系统的余热回收和降低燃油消耗率的方法。他们认为油冷柴油机有如下几个优点:1.气缸套冷却温度能升到100℃或在大气压下还可以高些,这可使热回收更能广泛应用,例如空间加热、饮用水加热、制水器及渣油和低品位油的加热等等:2.冷却缸套内无腐蚀产生,则使冷却部分的使用寿命延长;3.由于发动机受热部分温度变高,缸套和活塞环中硫腐蚀则变少了,这对低质重油发动机来说是很重要的:4.由于燃烧室壁温较高,燃烧效率可以改善,燃油消耗率可降低2%:
Japan Matsui Iron Works to study and develop a medium-sized marine diesel engine oil cooling system waste heat recovery and reduce fuel consumption rate. They consider the following advantages of oil-cooled diesel engines: 1. Cylinder liner cooling temperatures up to 100 ° C or higher at atmospheric pressure can make heat recovery more widely available, such as space heating, potable water heating, Water and residual oil and low-grade oil heating, etc.: 2. Cooling cylinder liner without corrosion, the cooling part of the service life is extended; 3. Due to the engine heat part of the high temperature, the cylinder liner and piston ring sulfur Corrosion is reduced, which is important for low quality heavy oil engines: 4. Combustion efficiency can be improved due to higher wall temperatures in the combustion chamber, reducing fuel consumption by 2%:
