For a company that had a meager capital of one million Yen, Isuzu had truly done something innovative to indulge in its current success and financial stability as one of the world leaders in the automobile industry. There is no denying that its development of diesel-powered vehicles plays a huge part in this triumph. It began in 1934 when Automobile Industries Co., Ltd. (the predecessor of Isuzu) formed a research committee that was tasked to study the engine. After two years, it finally introduced the first air-cooled diesel engine to be used in vehicles. From that period, the company started the production of diesel cars and in 1941, only Isuzu Motors was allowed by the Japanese government to produce this type of vehicles.
The DA80 diesel engine
When the war came to a halt, a lot of industries struggled to get back on track. Isuzu bounced back alive and kicking when it presented to the market the DA80 diesel engine, which is the first V8 engine in Japan. This engine attracted people's attention for its faster and higher performance features.
The TX61 dump truck
Destruction and fuel shortage struck Japan after World War II. To address these problems, Isuzu created the TX61 bonnet-type truck which is powered by the DA640 diesel engine in 1959. This truck was not only fuel-efficient, but also strong and sturdy. It was what the country needed to start reconstructing damaged establishments.
In 1961, Isuzu made the DL201 available in the market; this was the first diesel-powered-passenger car. Isuzu Motors received the Technological Award from the Japan Society of Mechanical Engineers for this innovation.
8PB1-T and 6RA1 turbo-charged engines
From 1981, Isuzu concentrated in making vehicles that boast speed and torque but save a lot of energy. The company incorporated this innovation to its trucks powered by 8PB1-T and 6RA1 turbo-charged engines. For cars, Isuzu made the Florian in 1977 and the Gemini in 1979. In 1981, Isuzu produced the first electronically powered diesel engines for both cars and trucks.
Eco-friendly Isuzu diesel engines
After these developments, Isuzu is now focused in creating innovations that uphold clean and green technological standards. Its aim is to promote awareness against global warming and climate change by continuing the search for ways to make low-impact and clean diesel engines. Examples of such innovations include turbo-charged and intercooled engines that increase fuel efficiency and emit fewer gases.
