| 1934: |
Automobile Industries Co.,
Ltd., an Isuzu predecessor, established a diesel research
committee |
| 1936: |
Isuzu manufactured Japan's
first air-cooled diesel engine, a breakthrough in the
history of diesel engine development. |
| 1950: |

advances, including turbocharged and intercooler diesel
engines. PA diesel engine noted for its light weight, high
output and low emissions. |
| 1979: |
Second oil crisis further spurred energy-saving
technological advances. Launched the high torque,
economical, turbocharged 8PB1-T and 6RA1-T engines. Promoted
the use of fuel-efficient diesel powered passenger cars. |
