An intake system of a V-type internal combustion engine equipped with a turbocharger. The intake system is has an air intake passageway which is branched at a branched section into first and second downstream air intake passageways which are respectively communicable with first and second banks of the engine. First and second throttle valves are disposed respectively in the first and second downstream air intake passageways. Intake air is bypassed from the branched section through the air bypass passage to an upstream side of the turbocharger compressor when the throttle valves are closed in order to prevent an excessive pressure rise in an upstream side of the throttle valves. The air flow through the air bypass passage is controlled by an air bypass valve disposed in the air bypass passage near the branched section.

An internal combustion engine is disclosed, which comprises a cylinder block having lubrication oil passages formed therein, the oil passages having a cylinder block opening at one longitudinal end of the cylinder block; a crankshaft operatively installed in the cylinder block, the crankshaft having one end portion exposed to the outside of the cylinder block from the one longitudinal end of the same; and a front cover structure attached to the one longitudinal end of the cylinder block. The front cover structure includes a first portion having an oil pump housing formed thereon; an oil pump device driven by the exposed end portion of the crankshaft, the oil pump device being received in the oil pump housing; a second portion having first and second oil passages formed therein, the first oil passage having one end connected to an outlet port of the oil pump device, the second oil passage having one end which is mated with the cylinder block opening; and an oil filter fixed to the second portion and fluidly connected to the other ends of the first and second passages.

An arrangement of cooling system for transversely mounted internal combustion engine is disclosed, which is compactly mounted in an engine room. The arrangement comprises a water pump driven by the engine to force the cooling water drawn thereto to flow into a water jacket of the engine, the water pump being positioned at one longitudinal end of the engine; a thermostat assembly positioned at the other longitudinal end of the engine; a suction passage for transferring cooling water from the thermostat assembly to the water pump; a first structure defining a first water outlet of the water jacket at a position near the water pump; a second structure defining a second water outlet of the water jacket at a position near the thermostat assembly; a bypass passage extending between the second water outlet and the thermostat assembly; a radiator located beside the engine and having inlet and outlet openings; an inlet hose connecting the first water outlet to the inlet opening; and an outlet hose connecting the outlet opening of the radiator to the thermostat assembly.

An intake manifold for a V-type multi-cylinder internal combustion engine provided with two banks each including a cylinder head. The intake mainfold comprises lower and upper intake air collectors which lie one upon another and located above one of the two banks. The intake air collectors are supplied with intake air from an air filter. A first group of branch runners are provided to connect the lower intake air collector with the cylinder head of one bank, while a second group of branch runners are provided to connect the upper intake air collector with the cylinder head of the other bank. The upper end section (connected to the lower intake air collector) of each of the first group of branch runners and the upper end section (connected to the upper intake air collector) of each of the second group of branch runners lie one upon another thereby to form a space required for an ignition device and installation operation therefor, between the adjacent branch runners in the cylinder head logitudinal direction.

Blasting devices, each comprising an explosive substance, a deflector, and a casing containing an incompressible fluid, the explosive substance, and the deflector are inserted into respective holes bored in a rock or the like at spaced apart positions, a tamper being thereafter stuffed in each hole, and the explosive substances in the holes are detonated simultaneously. A shock wave or blast wave is thus created in the incompressible fluid in each hole, and is deflected by the deflector in a direction along which the rock or the like is to be fractured. An improved construction of the blasting device for practicing the method is also provided.
