1930:Cornelis Kramer’s critical view on the limitations of existing marine engines inspired him to design and fabricate one by himself. Together with his mechanical engineer Klaas Beekhoven, he developed the ‘Kramer Engine’ in 1930. Thishot bulb engine was provided with a coil disk that ran along with the crankshaft. Hence additional scavenging air was sucked in, which resulted in a very high efficiency. The power of this small 15HP 1-cylinder was equal to, for instance, that of the much larger Kromhout hot bulb engine. The Kramer Engine has a piston with a length of 30cm when drilling, which implies an interior cylinder length of 160/170. In addition to the 15HP 1-cylinder, a 30HP 2-cylinder engine was put into production as well.
