Abstract: PURPOSE: A device for testing a valve train is provided to obtain correct data and to reduce the time for testing by removing variable factors and applying a desired pressure. CONSTITUTION: A cylinder head assembly(CH) drives cam shafts(22,24) by a drive source and a power transmission tool. A testing unit(10) prepared in the lower portion of the cylinder head assembly is supported horizontally on a surface plate. The testing unit transmits a proper variable pressure to valves(26,28) of the cylinder head assembly. A temperature and hydraulic controller supplies the temperature and oil pressure generated from an engine to the cylinder head assembly.

Abstract: PURPOSE: A fuel injection nozzle integrated with a preheating plug is provided to easily design a cylinder head, to reduce cost and to prevent cracks due to the installation of a preheating plug by directly mounting a preheater at the front end of a fuel injection nozzle. CONSTITUTION: A preheating plug(3) for preheating a mixture is integrally formed at the front end of a fuel injection nozzle(2) mounted in a cylinder head(1). The hollow core cylinder shaped preheating plug has a housing(3a) having a threaded portion, a heating resistant coil(3b) radially coiled in the housing, and a terminal(3c) connected with the coil in contact with the terminal of the fuel injection nozzle. The housing of the preheating plug is combined with the fuel injection nozzle through thread connection. The terminal of the preheating plug is connected with the terminal of the housing, and power is supplied to the heating resistant coil via the terminals. Then, the heating resistant coil is heated and the heat is transferred through the housing to preheat the mixture in a combustion chamber.
