49cc Diesel Moped [The Angstrom]
249cc Diesel Motorbike
349cc Diesel Motorcycle


The 49cc diesel Angstrom is designed to comply with moped laws in the USA and other nations. The engine is designed to pack as much power into 49cc as possible. The pair of Otto2.0-stroke cylinders should run upwards of 10krpm and attach to a moped CVT.

Diesel produces 1Hp per 54,000 cc/m. 49cc [50cc] operating at 10krpm produces 9.2 Hp in 4-stroke engines. The Otto2.0 should produce about 18Hp in ~50cc. A CVT will move this promptly to the road, and the moped will most likely be capable of moving faster than 30mph. A governor will likely be added to the moped to limit the speed and make the bike legal for sale. Larger than standard shocks and wheels will likely be standard. Easily tweakable [dial-up] modifications to the breathing cycle of the Otto2.0 will be produced.

A 150cc version would produce about 54Hp. The 250cc version should produce about 90Hp, and produce a highway-level motorcycle performance, with greater than average acceleration and in the light of acceleration diesel tuning, a top speed of ~90mph. A 350cc motorcycle would be the next step up, producing 126Hp, for an experience more like a touring bike.

Hello,
Does the 49cc diesel engine exist or is it just in the design phase?

Howdy! The 49cc diesel is still on paper. How would you make one, friend? We're thinking 4 x-firing microcylinders with cooling fins and liquid. One trick is how high to set the rpms to get the most power and engine life.
