5. Engine usage

5.1 Oil system

Only Castrol Edge Titanium 10W60 can be used in the MR18 F3R

engine.

Oil filter is changed also after the bench breaking-in and power curves. Make sure to clean carefully

all oil pipes and oil tank (in bellhousing) before you mount a new or rebuilt engine in the car.

5.2 General:

Extreme care must be taken with the routing of all wiring looms

and positioning of equipment to avoid damage to wiring insulation

or over-stressing of internal cables.

Prevent the engine loom and the ECU loom from unlikely conditions that could cause damages:

- do not crush the loom.

- avoid friction on sharp or exposed edges.

- use preventive devices such as rub wraps where it is necessary.

- design a proper thermal insulation in order to protect the alternator and its loom.

- make sure that all electronic devices are properly fixed and cannot be damaged by vibrations.

5.3 Maintenance after each event:

- check the loom and all connectors.

- check all power connections on alternator, electric starter, chassis ground and power.


5.4 Engine Wiring Overview:

5.5 Engine sensors installed on chassis:

Your car is equipped with engine sensors installed on chassis, make sure they are in a good status at

all time:

- Lambda Bosch sensor

- Barometric pressure sensor.

5.6 Lambda sensors important note:

Please ensure that a small amount of Copper grease is applied to the threads prior to fitting.

The Lambda Sensors fitted to each exhaust tail pipe are very

sensitive items and therefore, care must be taken to ensure that

they are not damaged.

5.7 Barometric pressure sensor important note:

Never install the sensor with the

inlet hole oriented to the top.

5.8 Air filter

Cotton air filter is an important and sensitive part. On dirty circuits, ensure to use exclusively new filter.

Keep in mind that a new filter is only pre-oiled; specific COTTON air filter oil (distributed by K&N, Green,

JR, DNA, others…) must be added on a new air filter (each side) before to install it.

OIL FOR FOAM AIR FILTER IS STRONGLY PROHIBITED.

Air filter can be cleaned and re-used. It is important that your air filter be clean (or changed) regularly

to ensure an optimum engine performance and reliability. This interval can be greatly influenced by

your environment and driving conditions. In dusty areas, you may need to clean the filter more often.

Please refer to section 6.2 of the engine manual for air filter cleaning procedure. ORECA recommends

to customers to have a minimum of 2 spare air filters and a complete air filter cleaning kit.


5.9 Frequency of maintenance

- Before each meeting, your air filter must be new (or cleaned)

- Clean it before the race (and clean it after the race)

- Dry your air filter after a wet practice / race

- Check your air filter if the car went in the gravel

- Change your air filter when it looks too dirty / old, or when the cotton does not still cover

the whole mesh of the air filter (if you see some holes in the mesh).

6. Starting procedure

6.1 Before starting

Before starting, you must ensure the following points:

- Coolant and engine oil at a correct level.

- Cold engine ONLY: open the water circuit up to 50°C water temperature.

- Proceed to Pedal/throttle/eWastegate learning before the first start of each meeting, or after any intervention on the throttle, pedal or Wastegate.

-Check all temps and pressure sensors.


-ELB state must be “Link ON” and limiter active “Std1”. Limiter apply will be 6750 RPM.

-check sensors and injectors supply. All Vrefs must be close to 5.000 Volts and Vtank must be close to

67 Volts.


6.2 Pedal/throttle/ewastegate learning

Pedal sensor voltages range

Pedal voltages must be in the below voltage ranges to able to success the learning.

Off pedal (0%) Full pedal (100%)

Min value (Volts)

Max value (Volts)

Min value (Volts)

Max value (Volts)

Pedal sensor RAW 1

1 3 3,1 4,9

Pedal sensor RAW 2

1,8 4 0,2 1,75

Pedal/throttle learning procedure: Duration approximately 30 seconds

1) Power off the car and press full throttle pedal while main switch is off.

2) Keep full throttle pedal, Turn ON main switch and keep full throttle pedal position for 6-7 seconds.

3) Release the throttle pedal (= remove completely the foot from it) and wait for the end of the

automatic pedal/throttle learning procedure (motorized throttles are going successively to MIN –>

MAX –> IDLE positions).

4) Make power cycle when learning is succeeded

It is possible to hear the motorized throttles during calibration. If

nothing happens, you must proceed to the complete

pedal/throttle learning procedure again.


6.3 Engine warm procedure

- Ensure Neutral gear is selected

- Ignition OFF, use starter button to make the oil pressure increase to 2bar (cold oil) or 0.5bar (hot oil).

Never use starter button longer than 5 seconds in the way to preserve the electric starter.

- The engine is now ready for starting

- Ignition ON

-When engine is running, Engine State is “RUNNING” and SyncState is “Phased”. In case of starting

issue, you can check SyncState. If this value is not “Phased” under cranking you can have issue with

crank our cam sensors

-Engine is running

Verify Oil Pressure Immediately after Start (4 – 6 Bars).

- Check VVT errors. VVT1 is Inlet camshaft and VV2 is Exhaust camshaft. Both VVT err must be close to

0° when engine is running.


- Keep the engine speed between 2000RPM and 2500RPM until the coolant temperature reaches

50°C. Adjust water level if necessary. At coolant temperature = 50°C precisely, close the water cap.

- At IDLE speed press clutch and engage 1st gear Shift up gently from 1st to 6th gear until the coolant

temperature reaches 65°C, then shift down slowly to 1st gear.

- 1st gear engaged, rise engine speed at 3000-3200RPM stable and shift up to 6th gear. Release throttle

pedal and shift down to neutral. Take care that coolant temperature do not exceed 75°C at this point.

- Check reverse gear and go back to neutral.

- At neutral, use engine speed of 4000RPM for 10 seconds and kill engine.

- Turn ignition OFF.

- Check the oil level asap after Ignition OFF

7. Engine usage

7.1 General precautions

Always run the engine with the correct oil and water levels. Under no circumstance water/humidity

can stay in the airbox. Ensure to have a cleaned air filter and airbox each day.

7.2 Operating temperatures and pressures

Coolant temperature:

Warming up / Bad use Normal operating Bad use

50 75 110

Engine oil temperature:

Warming up / Bad use Normal operating Bad use

50 70 140


Engine oil pressure:

Bad use Normal operating Bad use

2.8 4 6

If an alarm is displayed during running, it is the teams responsibility

to bring the car into the pits. If an alarm is ignored the team will be

responsible for any damage which may be caused to the engine.

7.3 Engine speed limiter

Engine speed is limited by the ECU at 6750RPM. It is tolerates to use the limiter during maximum 3

seconds continuously.

We have 2 separate limiters:

Absolute IGNITION LIMITER: 6750 RPM (above this value the ECU doesn’t fire any cylinder)

To get smother limitation there are 2 pre‐limiter band (one for IGNITION and one for INJECTION). The

pre‐limiter band is setup at 50 RPM from 1st to 6th gear under absolute limiter. This means that the

engine starts limiter is 6700 RPM.

For Neutral and reverse, Rev limiter is 4000 RPM


8. Engine maintenance

8.1 Maintenance table

8.2 Air filter cleaning procedure

Air filter is a key point for turbocharger reliability.

Read carefully this note before proceeding to the air filter

cleaning. Do not use high pressurized water (KARCHER). Hot water

(30°C) provides best result.

To clean your Green High Performance Air Filter, follow the steps below:

1. PRE-CLEANING

Tap the filter or blow with air to remove excess dirt.

2. APPLY CLEANER

Spray the filter with Green Filter Cleaner and allow the solution to soak in for about 15

minutes. The filter must not become dry

* Never use strong detergents, high pressure water, or gasoline.


3. RINSE

Rinse the filter with warm water, clean side to dirty side to flush out the dirt.

4. DRYING

Allow the filter to dry naturally. Try to avoid heat because it might shrink the cotton. If you use an air

gun, do not blow closer than 30cm from the air filter and do it carefully, otherwise the air flow will

generate holes

5. APPLY OIL

Re-oil the filter using Green Filter Oil by using 1 spray per 2 square inches of filter. Take care to not

over-oil your filter. Remove the excess of oil on the rubber. Air filter is ready to use. OIL FOR FOAM

AIR FILTER IS STRONGLY PROHIBITED

* Never use motor oil, transmission fluid, WD-40®, or any other brand of filter oil as these

may damage your Green Filter. Use only genuine Green Filter Oil.

8.3 Spark plug replacement procedure

Spark plug replacement is requested at 5,000kms from last rebuild achieved. Use exclusively spark

plugs set 7711168144.

- Remove carefully the coils and blow air prior to remove the old spark plugs.

- Remove old spark plugs.

- Apply a small amount of copper grease on the threads of new spark plugs.

- Assemble the new spark plugs. Torque it by hand to compress the seal. Release it and torque it again

at 17Nm.

Special care must be taken when fitting back the coils.

Ensure that the coil connector number fits on the correct

cylinder number.


8.4 Oil filter replacement procedure

Use exclusively oil filter P/N: 1520865F0B.

- Clean carefully the oil filter area prior to remove the old one.

- Remove old oil filter.

- Apply a small amount of oil on the seal of the new oil filter.

- Assemble the oil filter and torque it at 20Nm. Verify minimum 3 times the torque (filter shouldn’t

move) and mark its final position with a paint pencil.

8.5 Clutch tightening procedure:

- Read and carefully follow the Sachs instructions enclosed in the clutch box.

- Apply Loctite 243 and torque clutch nuts at 22Nm.

DON’T FORGET TO REMOVE THE INSTALLATION CLIP!

8.6 Fly wheel tightening procedure:

- It is recommended not to use the flywheel screws several times.

- Before tightening, apply copper grease or ARP grease on the thread and on the underside of the

screw head and torque fly wheel screw at 90 Nm.
