马自达研制出新一代V6型发动机。它有2.5L、2.0L和1.8L三种机型。研制目标是具有高性能,即优越的加速性和满足净化、经济的需要。此外,发动机运行声音应轻柔。为此马自达确定该发动机采用短行程、V型60°夹角、24气门双顶置凸轮轴、铝合金缸体的方案。研制中采用了四项技术:改善燃烧、优化控制以达到高燃油经济性和低排放;提高容积效率、减少旋转件惯性质量,达到优越的加速性;缸体和曲轴采用高刚度设计,缸体分上下两段,减少往复运动件质量,使发动机运行声音轻柔;选用轻质材料,去除多余空间使发动机结构更为紧凑,轻量。
Mazda developed a new generation of V6 engine. It has 2.5L, 2.0L and 1.8L three models. Development goal is to have high performance, that is superior acceleration and meet the purification, economic needs. In addition, the sound of the engine should be gentle. To this end Mazda to determine the engine with a short stroke, V-60 ° angle, 24-valve double overhead camshaft, aluminum alloy cylinder program. Four technologies were used in the development: improved combustion, optimized control to achieve high fuel economy and low emissions; increased volumetric efficiency, reduced inertial mass of the rotating parts and superior acceleration; high rigidity design of the cylinder block and crankshaft, Divided into two parts, up and down to reduce the quality of reciprocating parts, the engine running sound gentle; use of lightweight materials, remove excess space so that the engine structure is more compact and lightweight.
