Why does Isuzu focus on diesel engines?


The predecessor of Isuzu began in 1916 at the Ishikawa Island Shipyard in Tokyo. In the environment where many companies were researching and developing automobiles at that time, it finally merged with a gas and electric company to form the "Auto Manufacturing Company". In 1934, the "Isuzu" trademark appeared, and was finally renamed "Isuzu Motors Corporation" in 1949. Although Isuzu has used gasoline engines briefly in the history of automobile production, it has always been famous for its diesel engines. On the one hand, this originated from the policy set by the early founders, and on the other hand, it is also related to the government policies at the beginning of the establishment.




In fact, from the Tokyo Ishikawa Island Shipyard in 1922, "Isuzu" began to cooperate with British Wolseley (wolseley) to produce A9 cars, but at that time did not have any own technology, more assembly. By 1933, the then president Tomanosuke Ghana believed that American gasoline cars had reached the million-level production level at that time, and the development of global diesel engines had just started, and only diesel engines could compete with European and American forces. Thus, Japan's first air-cooled diesel engine was born in 1936. At that time, the technician Masao Ito who led the research and development was also known as the "father of Japanese diesel engines", and then devoted his life to the development of Isuzu diesel engines.


In 1941, Isuzu was the only automobile manufacturer approved by the Japanese government to produce diesel vehicles, while others such as Toyota and Nissan could produce gasoline vehicles. At that time, other unapproved manufacturers were not allowed to produce diesel vehicles, such as Mitsubishi Heavy Industries, Hitachi, and Kawasaki. They could only indirectly participate in the production of diesel vehicles by investing in them.


For this reason, Isuzu Motors was also called "Diesel Automobile Industry Co., Ltd." at that time. It can be said that in the early days of the development of Japanese diesel vehicles, Isuzu was also due to policy monopoly, which laid the foundation for it to become a professional diesel hegemon in Japan.




By 1949, "Diesel Automobile Industry Co., Ltd." was officially renamed "Isuzu Motors Co., Ltd.", and has since become known as "Diesel Isuzu". Of course, Isuzu also lived up to expectations and was eventually famous all over the world
