Although Diesel was born in Paris, he held German citizenship and identified as German. His parents were Bavarian immigrants, and he spent much of his life in Germany. Official records list him as a German inventor. source
Rudolf Diesel is best known for inventing which type of engine?
Diesel engine
Steam engine
Electric motor
Gasoline engine
Diesel is credited with inventing the compression-ignition engine that bears his name. His design used high compression to ignite fuel without a spark plug. This innovation is the basis for modern diesel engines. source
What was the original fuel Rudolf Diesel used in his early engine tests?
Peanut oil
Coal gas
Diesel fuel
Kerosene
In his 1890s experiments, Diesel ran his prototype on peanut oil, demonstrating that vegetable oils could power an internal combustion engine. He wanted to promote agricultural products as sustainable fuels. This fact highlights early biofuel concepts. source
What was the name of Rudolf Diesel's wife?
Martha Flasche
Lina Flairich
Else Katherina
Anna Deinhardt
Rudolf Diesel married Martha Flasche in 1898. The couple maintained a private life, and Martha supported his work behind the scenes. Details of their marriage are noted in several biographical sources. source
In which year was Rudolf Diesel's engine patent filed in Germany?
1892
1887
1901
1895
Rudolf Diesel filed his patent for the compression-ignition engine in Germany on February 23, 1892. The patent detailed the principles of a high-compression engine without spark ignition. It was officially granted as German Patent No. 67207 in 1893. source
What thermodynamic cycle does the diesel engine operate on?
Diesel cycle
Otto cycle
Stirling cycle
Brayton cycle
The diesel engine operates on the Diesel cycle, named after Rudolf Diesel. Unlike the Otto cycle, it features constant-pressure heat addition. This cycle is optimized for higher efficiency at high compression. source
In what year did Rudolf Diesel mysteriously disappear at sea?
1913
1910
1915
1920
Rudolf Diesel disappeared on the night of September 29–30, 1913, while crossing the English Channel aboard the SS Dresden. He was en route from Belgium to England and was never seen again. His disappearance remains a historical mystery. source
Which company built the first commercial diesel engine based on Diesel's patent?
MAN
Siemens
Krupp
Daimler
Maschinenfabrik Augsburg-Nürnberg (MAN) manufactured the first successful diesel engine under license from Diesel. They unveiled the prototype in 1897, proving its practical viability. MAN later became a major diesel engine producer. source
Where did Rudolf Diesel first publicly demonstrate his engine?
Augsburg
Munich
Berlin
Hamburg
Rudolf Diesel's first public demonstration of his engine took place in Augsburg in 1897. The demonstration proved the engine's ability to run continuously under load. It marked a turning point for industrial adoption. source
Compared to the Otto cycle, Diesel's cycle adds heat under which condition?
Constant pressure
Constant volume
Isothermal
Adiabatic
In the Diesel cycle, heat is added at constant pressure, unlike the Otto cycle which adds heat at constant volume. This allows variable cutoff points and improves efficiency. The constant-pressure heat addition is a defining feature of the Diesel cycle. source
What compression ratio did Diesel specify for his original engine design?
14:1
8:1
10:1
20:1
Rudolf Diesel’s initial engine design called for a high compression ratio of around 14:1 to achieve self-ignition of the fuel. This high compression was critical to his cycle’s efficiency gains. Modern diesel engines often use similar or higher ratios. source
How much horsepower did Diesel's first successful engine produce?
13 hp
4 hp
24 hp
50 hp
The prototype Diesel engine built in 1897 delivered about 13 horsepower (approximately 9.7 kW). This output demonstrated the engine's potential for industrial use. It was a major milestone in internal combustion technology. source
What is the title of Diesel's own book describing his heat motor theory?
Theory and Construction of a Rational Heat Motor
Internal Combustion Theory
Thermodynamics of Engines
Principles of Heat Engines
Rudolf Diesel published his ideas in 1893 under the title "Theory and Construction of a Rational Heat Motor." The treatise laid out the principles of his compression-ignition engine. It is regarded as the foundational text for diesel engine theory. source
What was the number of Diesel's original German patent for his motor?
67207
75000
12345
58912
Rudolf Diesel’s engine patent was officially registered as German Patent No. 67207 on February 17, 1893. This patent outlined the key innovations of his compression-ignition engine. It remains a landmark document in engine history. source

Cheat Sheet

  1. Early Innovation & Education -

    Rudolf Diesel's engineering journey began at the Royal Bavarian Polytechnical School, where he honed skills in thermodynamics and mechanical design. Use the mnemonic "Rooftop Discovered Ingenious Solutions" to remember his name and inventive spirit. This academic grounding laid the foundation for his landmark diesel engine (source: Technical University of Munich archives).

  2. Compression-Ignition Principle -

    Unlike Otto-cycle engines, Rudolf Diesel's design relies on high compression ratios (often >14:1) to auto-ignite fuel without a spark plug. Remember "CI = Compression Ignites" to distinguish diesel engine inventor facts from gasoline engines. This principle boosts power density and fuel flexibility (source: SAE International Journal).

  3. Thermodynamic Efficiency -

    The diesel cycle's ideal efficiency η ≈ 1 - (1/r^(γ−1)) often reaches 45 - 55%, far above gasoline counterparts. For quick recall, "High r, High Return" links compression ratio r to better fuel economy. These gains are documented in energy engineering texts at MIT and ETH Zürich.

  4. Rudolf Diesel Wife & Personal Life -

    Rudolf Diesel married Martha Flasche in 1883, and they had three children together, blending personal devotion with technical pursuits. A simple memory trick is "Martha Matters Most," highlighting his wife's support during prototype trials. Family correspondence preserved at the German Museum offers deeper Rudolf Diesel biography insights.

  5. History of Diesel Engine Impact -

    After patenting his design in 1892, Diesel's first successful MAN engine in 1897 delivered 16 kW at 90 rpm, revolutionizing marine and industrial transport. Recall "Diesel Drives Deep Distances" to link his invention to global shipping and rail. This legacy endures in modern heavy-duty engines (source: MAN Group historical archives).
