A tool set for detecting leakage of vehicle engines in the invention includes a support holder having a base, a frame, an adjusting plate and a coupling member; a leakage-detecting device having at least one connecting member and a connector-tube assembly provided with a pressure gauge and a switch.
A tool set for detecting leakage of vehicle engines in the invention includes a support holder having a base, a frame, an adjusting plate and a coupling member; a leakage-detecting device having at least one connecting member and a connector-tube assembly provided with a pressure gauge and a switch. In using, firstly use the support holder to hold an axle center of an engine crankshaft stationary. Secondly, screw the connecting member with a spark plug hole and connect the connector-tube assembly with a general air pump through which air is injected into an engine cylinder. Finally, when the cylinder is full of air, turn off the switch and observe an indicator needle of the gauge for reversing movements to determine whether any leakage occurs from the engine, thus providing a tool set for detecting leakage of vehicle engines that is timesaving, laborsaving and convenient in operation by a single person.

1. A tool set for detecting leakage of vehicle engines comprising:a support holder capable of holding an axle center of an engine crankshaft stationary, and consisting of a base, a frame, an adjusting plate and a coupling member;a leakage-detecting device adapted to detect leakage of an engine, and having at least one connecting member and a connector-tube assembly;each said at least one connecting member having one end provided with a first and a second threaded portion of different diameters for being selectively connected with spark plug holes of different sizes and the other end capable of being coupled to said connector-tube assembly;said connector-tube assembly provided with a pressure gauge as well as a switch, and having one end capable of being coupled to said at least one connecting member, and the other end capable of being connected with a general air pump; and,whereby in using, firstly use said support holder to hold said axle center of said engine crankshaft stationary, secondly connect said leakage-detecting device respectively with any one of said spark plug holes and said general air pump by having said first and said second threaded portions of said one end of said at least one connecting member connected with said spark plug hole and having said the other end of said connector-tube assembly connected with said general air pump through which air is capable of being injected into an engine cylinder, thirdly when said pressure gauge indicates that sufficient air is injected into said engine cylinder, turn off said switch and observe an indicator needle of said pressure gauge over a period of time for any reversing movements to determine whether any leakage occurs from said engine, thus providing a tool set for detecting leakage of vehicle engines that is timesaving, laborsaving and convenient in operation by a single person;said base of said support holder has two combining plates disposed at an upper surface thereof, each of said two combining plates provided with a screw hole, an insertion recess formed inbetween said two combining plates for being inserted by said frame of said support holder;wherein said frame of said support holder has a screw hole disposed at a lower portion thereof, at least one stud disposed at an appropriate place thereof and two rails respectively protruded at both sides thereof, said screw hole capable of being aligned to and combined with said screw hole of said two combining plates of said base by a screw member, a sliding way formed inbetween said two rails for being accommodated with said adjusting plate of said support holder;wherein said adjusting plate of said support holder has an elongated hole disposed in a middle portion thereof for being extended through by said at least one stud of said frame capable of be screwed tightly by a nut member to secure said adjusting plate in place, and a locating hole disposed at an upper portion thereof, said locating hole capable of being inserted through by said coupling member of said support holder and provided with points formed on an inner edge thereof; and,wherein said coupling member of said support holder is provided with at least one resilient projection disposed thereon, and has one end capable of being inserted through said locating hole of said adjusting plate and the other end capable of being fitted into a general socket. 2. The tool set for detecting leakage of vehicle engines as claimed in claim 1, wherein each of said two combining plates provided with a plurality of engagement slots, and said frame of said support holder has a plurality of engagement slots disposed at a lower portion thereof, at least one stud disposed at an appropriate place thereof and two rails respectively protruded at both sides thereof, said plurality of engagement slots of said frame capable of being aligned to and combined with said plurality of engagement slots of said two combining plates of said base by a locating pin.
