Setting up a belt drive, Ring Flutter, Pressurised airboxes and fluid diodes. The fluid diodes have the potential to boost power mid-range by over 20% so why are they not in common use? The pressurised airbox attempts to resonate in sympathy with the inlet tract, Helmholtz gave the methods, but the maths is significant. As with the silencer design, I will provide all the maths in a spreadsheet.
VSIH contains the theory and practice for the maintenance and improvement of post WW2 British two-stroke engines, typified by the Villiers and Greeves engines of the 1950's and 1960's. The illustrations reference Villiers 9E and 32A engines but the instruction equally applies to the Greeves, British Anzani, Excelsior, Alpha, Upton, Marcelle, Parkingson and Ajax two-stroke engines. Instruction includes port timing and measurement, crank (re)balancing, carburettor sizing, exhaust design and manufacture, silencer design and manufacture, and the chemistry of combustion. Worked examples and reference tables are provided, also photographs of the author's successes and failures. The book provides an intermediate level core of theory and practice that bears repeated reading to gain a full understanding.
