Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time. It employed a hemispherical cylinder head, chain-driven single overhead camshaft (SOHC) and eight valves (two per cylinder). United States passenger car versions had a small secondary intake valve referred to as the 'Jet Valve'. This valve induced swirl in the intake charge, enabling the use of leaner fuel/air mixtures for lower emissions.

It was designed as a cartridge containing the valve spring and seat which simply screwed into a threaded hole in the head, similar to a spark plug but inside the cam cover. The rocker arms for the intake valve were widened on the valve end to accommodate the cartridge, which was equipped with a very soft valve spring in order to avoid wear on the camshaft intake lobe.

After removing the power steering oil pump assembly, secure it with a cord in the location where the removal and installation of the vacuum pump assembly cannot be hindered.

Modifications to the head were thereby reduced as the Jet Valve negated the necessity for a three-valve-per-cylinder design. In 1975, the Astron 80 introduced a system dubbed 'Silent Shaft': the first use of twin balance shafts in a modern engine. It followed the designs of Frederick Lanchester, whose original patents Mitsubishi had obtained, and proved influential as Fiat/Lancia, Saab and Porsche all licensed this technology.

The 4D5 engine is a range of four-cylinder belt-driven overhead camshaft diesel engines which were part of the 'Astron' family, and introduced in 1980 in the then new fifth generation Galant. As the first turbodiesel to be offered in a Japanese passenger car, it proved popular in the emerging SUV and minivan markets where Mitsubishi was highly successful, until superseded by the 4M4 range in 1993. However, production of the 4D5 (4D56) continued throughout the 1990s as a lower-cost option than the more modern powerplants. Until now it is still in production, but made into a modern powerplant by putting a common rail direct injection fuel system into the engine.

ON-VEHICLE SERVICE ENGINE MECHANICAL 11A-8 CAUTION. The temperature of the surface of the belt should be as close to normal temperature as possible. Do not let any contaminants such as water or oil get onto the microphone. If strong gusts of wind blow against the microphone or if there are any loud sources of noise nearby, the values measured by the microphone may not correspond to actual values.

If the microphone is touching the belt while the measurement is being made, the values measured by the microphone may not corre- spond to actual values. Do not take the measurement while the vehi- cle's engine is running. AC903689 15˚ 15˚ MB992080 (Microphone) 10 – 15 mm AB Tensioner pulley Crankshaft pulley A/C compressor pulley 5. Hold special tool MB992080 to the middle of the belt between the pulleys (at the place indicated by arrow) where it does not contact the belt (approximately 10 − 15 mm away from the rear surface of the belt) so that it is perpendicular to the belt (within an angle of ± 15 °).

6. Press the 'MEASURE' button. 7. Gently tap the middle of the belt between the pulleys (the place indicated by the arrow) with your finger as shown in the illustration, and check that the vibration frequency of the belt is within the standard value.

NOTE: To take the measurement repeatedly, fillip the belt again. WHEN USING THE TENSION GAUGE AC506003AB Tensioner pulley Crankshaft pulley A/C compressor pulley Tension gauge Use a belt tension gauge in the middle of the belt between the pulleys shown in the figure (at the place indicated by the arrow) to check that the belt tension is within the standard value.

BELT DEFLECTION CHECK AC506004AB Tensioner pulley Crankshaft pulley A/C compressor pulley Approximately 100N Deflection Apply approximately 100 N of pressure against the location between the pulleys shown by the arrow in the illustration and then measure the deflection. When the belt tension is adjusted by measuring the belt deflection, adjust it with a tool for vibration fre- quency measurement or tension measurement after- ward. BELT TENSION ADJUSTMENT If not within the standard value, adjust the belt ten- sion by the following procedure. AC505988AB Adjusting bolt Locking nut Tensioner pulley 1. Loosen the locking nut of the tensioner pulley. ON-VEHICLE SERVICE ENGINE MECHANICAL 11A-9 2. Use the adjusting bolt to adjust the belt tension. The tension will increase when turning the adjusting bolt clockwise, and decrease when turning anti-clockwise. 3. Tighten the locking nut.

4. Tighten the adjusting bolt. CAUTION When checking the belt tension, turn the crank- shaft clockwise one turn or more. 5. Check the belt tension, and readjust if necessary. AUTO-TENSIONER CHECK M216 OPERATION CHECK 1. Turn off the engine from the idle state then check to see that the drive belt is not protruding from the pulley width of the auto tensioner. 2. Remove the drive belt (Refer to ).

AC501804 AC507703 Auto tensioner AB 3. Install the tool to the auto tensioner, and check that no binding is present by turning the auto tensioner in the left and right directions. 4. If there are any problems in the procedure 1 or 3, replace the auto tensioner (Refer to 5. Install the drive belt (Ref FUNCTION CHECK You can verify if the auto tensioner is defective or not by checking the drive belt tension. When the vibration frequency is measured (Special tool MB992080 is used): Recommendation 1. Check the drive belt tension (Refer to ). 2. Measure the drive belt tension vibration frequency by the following procedures: AC507219AB MB992082 MB992081 Belt tension meter set (MB992080) (1) Connect special tool microphone assembly (MB992082) to special tool belt tension meter (MB992081) of special tool belt tension meter set (MB992080).

(2) Press the 'POWER' button to turn on the power supply. (3) Press the numeral key of '1' and check that 'No.1' appears on the upper left of the display.

NOTE: This operation is to temporarily set the preset data such as the belt specifications, because if the measurement is taken without input of the belt specifications, conversion to tension value (N) cannot be made, resulting in judgement of error. (4) Press 'Hz' button twice to change the display to the frequency display (Hz). ON-VEHICLE SERVICE ENGINE MECHANICAL 11A-10 CAUTION. The temperature of the surface of the belt should be as close to normal temperature as possible. Do not allow any contaminants such as water or oil to get onto the microphone.
