The invention relates to transport engineering and serves for starting combustion engines with a large cylinder capacity and transmission elements (trucks, agricultural engineering, building engineering, mining engineering).

In an inertia engine transmission elements are used as a rotating mass (a flywheel).

The method of engine start includes a preliminary accumulation of mechanical energy in the system to be a peculiar flywheel and then transmission it to a crankshaft of engine.

The starting inertia system consists of usual, regular parts that form a transmission, and includes: flywheel 1, clutch disk 2, clamping plate 3, throw-out bearing 4, starting gear 5 located at primary shaft 11, gear box 12, starter gear6, starter 7. See fig 1.

An engine start is carried out as follows:

A driving mechanism (throw-out bearing 4, clamping plate 3, see fig. 2) presses a clutch . In this case the clutch disk 2 backs off from the flywheel 1, fig 2. A voltage is applied to the starter 7 from an accumulator battery. Starter gear 6 engages with starting gear 5 and becomes to rotate it. As the gear 5 is fastened at the shaft, the system consisting of clutch disk 2 not pressed to the flywheel 1, the primary shaft of gear box 11 comes into rotating. See fig2.

After the above mentioned system has picked up maximum number of rounds (0,8-1,5 seconds), the clutch disk 2 is pressed to the flywheel 1 by the driving mechanism (throw-out bearing 4, clamping plate 3, fig.1). The disk 2 transfers a rotating motion to the flywheel. Engine starting occurs. The starter is switched off.

Powers of a starter an accumulator can be one-third as large as at direct starting. A starting freguency riches a value of 2,5 times as much as a minimum freguency that provide a sufficient reliable start of engine (especially in the winter period). A large starting freguency secures also more ecologically clear exhaust in starting. As shown above, lesser power of as a starter, so an accumulator provides their lesser prime cost.
