Research of dynamic phenomena in a model engine stand

Abstract The highest loads on the elements of crank–piston system internal combustion engine occur during phase which takes place successively in individual cylinders. Smaller, but also significant, beyond this when dynamic forces begin to play a dominant role. latter depends degree wear components. aim article was analyze stresses model stand for testing phenomena an operating without process. A has been developed includes driven by electric motor placed mobile frame. coast-down method used estimate average values equivalent moment inertia various cylinder configurations with lack compression process due significant weakening valve springs or seats. This simulated bench partially loosening spark plug mounting. presents determined mean and stress frame obtained from its use finite element method. were important point view dynamics simulation outside area safe foundation operation experimental tests.
