Injector instruction sheets List of checks The purpose of this procedure is to check a number of points before and after dynamometer testing. It is suited to engines with electronic control (TIER III).

Failure to carry out these tests may lead to an incorrect power reading.

Always check the following points before starting a PTO power test.

Reminder: Wait until the running-in period has elapsed (minimum 100 hours) before testing an engine on the dynamometer.

This period is necessary to ensure that measurements are carried out under suitable conditions.

1. Visual checks Make sure that the supply and return lines are correctly fitted (not trapped or kinked on installation, etc.). Check that the engine serial n° read with Métadiag is the same as the one indicated on the engine identification plate and if there are any error codes.

2. Engine oil level Check the fluid level with dipstick (1):

l

I Normal operating level.

ll

II Top up as soon as possible.

lll

III Top up before restarting the engine.

Fig. 7

3. Hydraulic /transmission oil level – Check the fluid level with dipstick (1).

– I: Normal operating level.

l

– II: Top up as soon as possible.

ll

– III: Top up before restarting the engine.

lll

– The fluid is topped up via the cap (2).

4. Battery Check the voltage with the engine stopped (between 12 and 13 V). Alternator-generated power consumption can reach 1,5 kW.

5. Radiators/coolers Check that all radiators/coolers are clean.

9. Checking the hydraulic pressure Check the hydraulic pressure while referring to the hydraulic pressure checks in this chapter. Make sure that no hydraulic application is running. If hydraulic pressure is not within the specifications, the PTO power test results will be affected.

10. Fit the dynamometer Before starting the test, ensure that: – The rig is correctly adjusted and calibrated.

– The CV joint is aligned, attached and protected.

– The tractor is chocked.

Position the tractor in an open area.

Injector instruction sheets 11. Position of the Quadrishift/transmission reverter (according to equipment) To limit transmission power take-off, make sure that: The reverser and the transmission are in neutral (See chapter “E” of the user's manual).

12. Air conditioning/Ventilation Ensure that the air conditioning and ventilation are switched off.

13. Front power take-off Make sure that the front power take-off is disengaged.

14. Viscous fan coupling To obtain the best possible measurement, the viscocoupler must not be locked. In addition, to ensure minimum slipping of the viscocoupler, perform the measurements with an ambient temperature of 35°C.

15. Check the maximum no-load rpm 2 325 ± 10 rpm.

16. Engage the PTO at the 1 000 rpm position 17. Run the engine at half load until the operating temperature is reached Coolant temperature: 80-90°C. Transmission temperature: 60-65°C.

18. Accelerate the engine to maximum rpm for 1 min 19. Measure the power (see injector instruction sheet) 20. After measuring, check the tractor temperature Coolant temperature:80-90°C. Transmission temperature: 60-65°C.

21. Leave the engine running at between 1 500 and 1 600 rpm for 3 to 5 minutes, then idle before switching off If the results do not match the manufacturer's data following these operations, a flowmeter will need to be installed and the values compared to the injection sheets.

The crankshaft position sensor B231 indicates the engine's rotation speed, as well as the precise crankshaft position (TDC of cylinders 1 and 6). This signal is hence used by engine speed and advance management.

If the signal transmitted by B231 is absent, the signal transmitted by B232 is used to manage engine speed. As the crankshaft position information is inaccurate, a power reduction is indicated.

The timing position signal B232 specifies which cylinder, 1 or 6, is at end compression TDC to synchronize injection with timing.

Functional logic Upon starting, the unit ENG manages the supply of the Y344 SV to obtain a pressure of about 300 bar in the rail.

The unit considers the coolant temperature to determine the overload and timing advance when starting.

If the ENG module does not detect any pressure signal or pressure below 100 bar after 5s, starting is no longer authorized.

The unit needs crankshaft (B231) and timing (B232) position information to select the cylinder to inject.

If the timing position signal (B) is absent, the ENG module supplies the injector 6 after each signal (E) indicated by the crankshaft sensor B231, until the engine starts ⇒ 1 crankshaft turn allows to find proper synchronism.

Full engine power is available.

by the timing position sensor (F), until the engine starts ⇒ 2 crankshaft turn allows to find proper synchronism.

As the timing position signal is not precise enough to manage ignition advance, power reduction is activated.

if the crankshaft position signal (A) is absent, the module ENG supplies the injector 1 when seeing the signal 1 sent

E Postheating cycle.

– When starting, the heating flange supply is stopped to facilitate the starter's operation [Zone (B) in the diagram above].

– If the engine speed fluctuates too much, the heating flange is supplied for 15 seconds, then the ENG module analyzes the regularity of the engine speed again.

– Transient postheating takes over when engine speed is > 100 rev/min and until idle speed is reached (800 rpm).

– If the engine speed is stable, postheating is suspended, otherwise it resumes for 15 seconds.

– Wuring the postheating cycle (E) the ENG module analyzes engine speed regularity.

The analysis cycle lasts 2 minutes maximum.

The “Powertech E” engine uses: – a highly advanced preinjection system in the engine cycle (up to 30° TDC). The low quantity injected generates CO2 in the thermal enclosure before combustion.

– The preinjection parameters depend mainly on the engine speed and load.

A1.42

– The timing diagram has been changed, and a volumetric ratio increased to allow compression pressure to be sufficient during pre-injection.

– A specific turbocharger is fitted to increase the filling rate.
