The invention discloses an engine test system. The engine test system comprises a support structure, the support structure comprises a lower layer, a middle layer and an upper layer, a pedestal is arranged from the bottom of the lower layer to the bottom of the middle layer of the support structure, the pedestal is provided with an engine support apparatus, and the pedestal is also provided with a dynamometer and an inter-cooling apparatus; a fuel oil supply apparatus, a machine oil supply apparatus and a water circulating apparatus which are connected with an engine are arranged from the lower layer to the middle layer of the support structure; a smoke evacuation apparatus is arranged from the upper layer to the middle layer of the support structure; an air inlet apparatus is arranged from the upper layer to the middle layer of the support structure; and a thermal shock apparatus connected with the engine is arranged at the outer side of the pedestal at the middle layer of the support structure. It can be known from the description of the scheme provided by the invention that the engine test system has the following advantages: the design is reasonable, the structure is compact, the cost is low, the engine test system is suitable for a V-type vehicular engine, a ship engine and a generator set, and the universality and the practicality are combined together; and the apparatus provided by the invention can also be applied to an engine automatic thermal shock circulating test and other routine tests.
Description
technical field [0001] The invention relates to a test system, in particular to an engine test system. Background technique [0002] Modern cars pay more attention to aerodynamics, requiring the smaller the windward surface of the car, and the lower the engine cover, the better. In addition, if the length of the engine is shortened, more space can be left for the cockpit. The V-type engine is to divide all the cylinders into two groups, and arrange the adjacent cylinders together at a certain angle, so that the two groups of cylinders form a plane with an angle, and the cylinders are V-shaped from the side. The height and length of the V-shaped engine are small, and it is more convenient to arrange on the car. It facilitates increased displacement and power by enlarging the cylinder diameter and is suitable for higher cylinder counts. In addition, the V-shaped engine cylinders are arranged opposite to each other, which can also offset part of the vibration and make the ...
