D The changes described below are the same as those of the 1HD FTE engine For details see the 1HD FTE. engine section,Item Details 1HZ 1HD T, D The rigidity of the cylinder block has been improved.
to reduce noise and vibration, D The crankshaft has been made highly rigid to reduce. Engine Proper f f,noise and vibration, D The crankshaft bearings have been machine bored to. improve their reliability,D An aluminum radiator core is used for weight. Cooling System D A step up linear type temperature controlled fluid f f. coupling has been adopted to improve cooling EG,performance. D A high performance oil filter element has been, adopted to improve the cleanliness of the engine oil.
D A drip pan is provided on the oil cooler cover to. Lubrication System improve serviceability, The oil capacity of the engine has been increased to. improve its reliability, D A ball joint has been adopted in the front exhaust pipe. Intake and to reduce noise and vibration, Exhaust System D A clamp type joint is used to join the center pipe and. tail pipe to realize weight reduction, D In addition to those listed above the following changes have been made to the 1HZ and 1HD T engines. Item Detail 1HZ 1HD T, D The shape of the combustion chamber of the cylinder.
head and the piston has been optimized to reduce,Engine Proper exhaust emissions f. D The inertial weight of the flywheel has been increased. to reduce the fluctuations in engine speed, D A hydraulic type auto tensioner has been adopted to. achieve proper timing belt tension,Valve Mechanism f f. D The shape of the timing gear cover has been changed. for quieter operation, D The orifice of the injection nozzle has been increased. to optimize the injection rate, Fuel System D The injection pump is provided with FCVC Fuel Cut.
Valve Control in conjunction with the adoption of the f f. engine immobiliser system, D New glow plugs made of metal have been adopted and. Glow System the glow plug resistor and sub relay have been f f. discontinued, Please purchase PDF Split Merge on www verypdf com to remove this watermark. 104 ENGINE 1HZ AND 1HD T ENGINES,JENGINE PROPER 1HZ ENGINE. 1 Cylinder Head, The shape of the combustion chamber has been optimized to reduce exhaust emissions. Combustion,New Previous, D The piston is made of aluminum alloy that offers high temperature strength The top ring groove has been.
treated with MMC Metal Matrix Composites to improve its wear resistance. D The shape of the piston skirt has been optimized to improve its rigidity Accordingly the steel strut has. been discontinued, D The shape of the combustion chamber at the top of the piston has been changed Along with the change. in the shape of the combustion chamber in the cylinder head improved combustion efficiency has been. Previous New,Steel Strut,Previous New Top of Piston. MMC Metal Matrix Composites, It is a type of composite material that is made of a metal matrix for the purpose of obtaining characteristics. such as high strength high elasticity and low thermal expansion Because of its excellent heat transmission. performance this material helps to dissipate the piston s heat through the piston ring to the cylinder block.

ENGINE 1HZ AND 1HD T ENGINES 107,2 Injection Pump, D Along with the changes made to the shape of its combustion chamber the 1HZ engine has realized optimal. injection volume injection characteristics and injection timing. D The injection pump is provided with FCVC Fuel Cut Valve Control in conjunction with the adoption of. the engine immobiliser system Upon receiving communication from the transponder key computer the. FCVC turns OFF the fuel cut valve to prohibit the engine from starting if an invalid ignition key is used. in an attempt to start the engine, D A tampering proof cap is placed over the full load setting screw on the models for the General Countries. Ignition FCVC,FCVC Switch,Transponder,Key Amplifier.
Battery Fuel,147EG125 147EG120,JGLOW SYSTEM,1 Glow Plug. D New glow plugs made of metal have been, adopted Using an optimal control coil material Thermal coil. and providing a temperature control function in,the glow plug itself the system has been. simplified by discontinuing the glow plug,resister and sub relay.
