This three-wheeled trike has been created for horticultural and domestic purposes; it is convenient to carry bags, tools and other small loads. The engine is the usual cycle motor D-6, widely used in garden partnerships to drive the rippers, cultivators, pumps, mowers. However, its design is intended for cooling from the oncoming air flow while driving.
To work in unfamiliar new environment needed to equip vasomotor forced cooling system, which I did in the manufacture of its trike.
Took the design published in the article “Waldwichtel on the tiller” (“M-K” № 8, 1979), but change it a bit, adapting to his car. Improvement of the engine is to install one of kostruykov crankshaft centrifugal fan enclosed in the casing. It directs the airflow to the most heat-generating parts: the cylinder head and upper part of the cylinder.
