The pistons are made of a special aluminium alloy. Their weight has been reduced by lowering their overall height and increasing the depression at each end of the piston pin. The piston pin hole centre is offset 0.8 mm towards the thrust side of the piston centre. The skirt portion along the perimeter of the piston is finished with streaks that excel in oil retention and seizure resistance.
2. PISTON PIN
The piston pin is of a semi-floating type, press-fitted into the connecting rod small end while capable of floating relative to the piston.
3. CONNECTING ROD
The connecting rod is made of highly rigid, forged carbon steel. The rod portion has an H-shaped cross section. The connecting rod big end bearing is lubricated through an oil passage running from the main journal to the crankshaft pin.
4. PISTON RING
Each piston is provided with No. 1 and No. 2 compression rings and an oil ring.
5. CONNECTING ROD BEARING
The upper and lower connecting rod bearing halves are identical. The connecting rod bearing is equipped with back metal. While the bearing itself is made of aluminium alloy, the back metal is normally made of steel sheet. The connecting rod bearing is narrower than the bearing cap, this is to minimize wear.


CRANKSHAFT RELATION
1. CRANK SHAFT
A casted crankshaft is used for the crankshaft. The crankshaft consists of five main bearings and eight balance weights. The crankshaft pins are arranged at 180° intervals. The oil hole supplies lubrication oil from the journal to the crank pin. A crankshaft sprocket and an oil pump drive gear shaft are shrink-fitted onto the front of the crankshaft.
2. CRANKSHAFT BEARING
The crankshaft bearing upper (with oil groove) is located on the cylinder block side while the crankshaft bearing lower (without oil groove) is held by the bearing cap.The crankshaft bearing is equipped with back metal. While the bearing itself is made of aluminium alloy, the back metal is made of steel sheet.
3. THRUST BEARING
A thrust bearing is installed on both sides of the No. 3 crankshaft bearing.
4. CRANKSHAFT PULLEY
The crankshaft pulley is made of cast-iron and rubber. The pulley has grooves to engage with a V-ribbed belt (six ribs), which drives an alternator and a water pump and an A/C compressor. An ignition timing mark (notch) is stamped on the flange of the pulley. The crankshaft pulley is equipped with a torsional damper to minimize the torsional vibration of the crankshaft as well as substantially reduce noise and vibration at the high speed range.
5. CRANKSHAFT SENSING RING
The crankshaft is also fitted with a crankshaft sensing ring.
6. DRIVE PLATE
A cast iron ring gear is a shrink fit in the steel plate of the drive plate. The drive plate is installed by tightening six bolts.


TIMING CHAIN RELATION
1. CRANKSHAFT FRONT OIL SEAL
A crankshaft front oil seal is press-fit into the case.
2. TIMING CHAIN CASE
The timing chain case is made of an aluminium alloy. A front crankshaft oil seal is press-fit into the case.
3. TIMING CHAIN
The two camshafts are driven by the timing chain via the camshaft sprockets. An endless type roller chain which consists of 142 links has been adopted for the timing chain. It is installed around the inlet V.V.T. sprocket, the exhaust camshaft sprocket and the crankshaft sprocket. Three link plates are installed on the timing chain to locate the sprockets.
4. TIMING CHAIN TENSIONER
The plunger in the timing chain tensioner directly pushes the tension lever, and the pressure automatically adjusts the timing chain tension. A cam is provided to lock the plunger in place after the engine stops. This helps prevent the timing chain from wobbling just after the engine starts. With the timing chain tensioner installed, do not crank the engine in the reverse direction. This will force the plunger to overcome the cam, or even cause other problems.
5. TENSIONER LEVER
6. TIMING CHAIN GUIDE
7. EXHAUST CAMSHAFT SPROCKET
8. INLET V.V.T. SPROCKET


VALVE RELATION
The valve mechanism is based on a 4-valve DOHC (Double Over Head Camshaft) design having the camshaft on the upper valve. Each cylinder has two inlet valves and two exhaust valves, arranged in a V-shape pattern.
Camshaft rotation is transmitted via valve tappets to the respective valves which open and close accordingly.
1. CAMSHAFT
2. VALVE TAPPET
Valve tappets are available in 47 thicknesses, at 0.015 mm intervals between 3.000 mm and 3.690 mm, to ensure correct valve clearance.
3. VALVE
The valves have heat-resistance. The entire valve surface is treated with nitriding.
4. VALVE STEM SEAL
The valve stem seals are integrated with the valve spring seats.
The valve stem seal portion excels in sealing performance and is equipped with a spring to prevent oil from descending.
5. VALVE SPRING
The valve spring has a dual pitch spring to prevent surging in the high speed range.


MIVEC (MITSUBISHI INNOVATIVE VALVE TIMING ELECTRONIC CONTROL SYSTEM) RELATION
MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) consists of the components illustrated above.
The inlet valve timing is optimally controlled (continuously variable) under the changing driving conditions to improve performance in the entire speed range.

V.V.T. SPROCKET (VARIABLE VALVE TIMING SPROCKET)
Oil from the oil feeder control valve is sent to the inlet V.V.T. sprocket, moving the vane rotor and thus regulating the valve timing.

CAMSHAFT
The lightweight camshaft is achieved by the hollow design.
Oil channels run through the inlet camshaft, through which oil is sent from the oil feeder control valve to the inlet V.V.T. sprocket.
The cam that detects the camshaft position is located at the rear end of the inlet camshaft.

OIL FEEDER CONTROL VALVE
The oil feeder control valve is essentially a solenoid valve, regulated by the engine-ECU signals to feed oil to the inlet V.V.T. sprocket assembly to move the vane rotor.

ENGINE LUBRICATION Mitsubishi Eclipce Cross <4B11> (21 Model year supplement)>
>>>Read<<<, >>>Read 2<<<
The lubrication system is the full-flow, filter pumping system.
The engine oil that accumulates in the oil pan is drawn and discharged by the oil pump. After its pressure is regulated by the relief valve, the oil passes through the oil filter. Then, it flows from the oil passage in the cylinder block to the individual crankshaft journals and the cylinder head.
After the oil is pumped to the individual crankshaft journals, it passes through a passage in the crankshaft and is fed to the pins. After the oil is pumped to the cylinder head, it flows to the camshaft journals and the oil feeder control valves.

1. OIL FILLER CAP
2. OIL LEVEL GAUGE
3. DRAIN PLUG
4. OIL PAN
The oil pan is made of sheet metal and contains an oil sump in the forward area of the engine.
FIPG (Formed-In-Place Gasket) is used to seal between the oil pan and the ladder frame.
note FIPG is the abbreviation for Formed-In-Place Gasket.
5. OIL FILTER
The oil filter is installed on the left side of the cylinder block.
6. OIL PUMP
The oil screen is integrated into the oil pump case to be compact and lightweight.
The oil pump case, which is installed to the bottom of the ladder flame, is driven by the oil pump chain through the oil pump sprocket installed to the front of the oil pump case.

• Fuel injector
• Fuel delivery pipe
• Fuel vapour canister
• Fuel high-pressure hose
• Fuel line pipe
• Fuel tank assembly
• Fuel pump and gauge assembly

This fuel system is designed with consideration for global environment protection to ensure safety at a collision, reduce weight, and improve reliability and quality. This system has the following features:
A quick-joint connector of a plastic tube is used for the fuel high-pressure hose in the engine compartment to reduce the permeation of fuel evaporative emission.
The surface of under floor fuel line pipes is coated with 1-mm thickness of resin to improve resistance to corrosion and chipping.
A return less fuel system eliminates returned fuel from the engine. The heat that fuel receives from the engine is reduced, minimising fuel temperature in the fuel tank and controlling the amount of evaporated gas.
The activated charcoal of fuel vapour canister is modified for downsizing, weight saving and better performance.
