He successfully tested his first prototype using peanut oil, a renewable resource that was readily accessible at the time. Diesel recognized that the air-fuel mixing process was a primary culprit in energy loss.
The Origins of Diesel Engine Efficiency and Rudolf Diesel's Innovation
However, Diesel’s persistence paid off in 1897 when he unveiled a four-stroke, single-cylinder diesel engine that achieved a then-unprecedented 75% thermal efficiency. Rudolf Diesel’s quest to invent a new form of power generation was never about chasing fame or designing a faster vehicle.
In 1913, the inventor mysteriously disappeared from a ship traveling to London, and his body was never found. The pressure to deliver a viable machine was immense, as investors grew wary of the project's complexity.
