The Duratec 1.8 engine was produced at the Valencia Engine plant from 2001 to 2010. This inline four-cylinder unit with an aluminum cylinder block and injection system has four valves per cylinder. The piston stroke is 83.1 mm and the cylinder diameter is 83 mm. The compression ratio of the engine is 10.8.
The engine displacement is 1,798 cubic centimeters. Engine output ranges from 115 to 125 horsepower at 6,000 rpm and torque reaches 165 Nm at 4,000 rpm.
Fuel with an octane rating of 95 is recommended for the engine, and it meets Euro 4 environmental standards. Fuel consumption is 9.5 liters per 100 km in the city, 5.6 liters per 100 km on the highway and 7 liters per 100 km in mixed mode. Oil consumption does not exceed 500 grams per 1000 km.
The dry weight of the Duratec 1.8 engine is approximately 93 kg. Geometric dimensions of the Focus 1.8 engine are not specified.
Recommended oil types for the engine are 5W-20 and 5W-30. According to the factory, the motor has a resource of about 350 thousand kilometers, but in practice its resource can reach up to 500 thousand kilometers.
There is no information about tuning and the potential to increase the engine power. Duratec 1.8 engine was installed in such cars as Ford C-Max Mk I, Ford Mondeo Mk III, Ford Focus Mk II, Mazda 5, Mazda 6 and Mazda MX-5.
Faults and repair of Focus/Mondeo/Fusion Duratec HE engine, Mazda 6 MZR 1.8
The Ford Duratec HE engine with a displacement of 1.8 liters and 125 horsepower, also known as Mazda MZR L8, was developed by the Japanese manufacturer as a development of the âFâ series of motors from Mazda. It was originally fitted to the Ford Mondeo, but was later upgraded to include an intake manifold duct management system with turbulizers, direct ignition system from ignition coils, electronic throttle and other improvements. According to the factory, the resource of the Ford Duratec HE/Mazda MZR L8 1.8 engine is 350 thousand kilometers, but in practice it can serve up to 500 thousand kilometers, provided regular maintenance.
Unlike the smaller Duratec, there is already installed a chain drive timing, which significantly increases reliability. However, the 1.8-liter motor has an inherent problem with floating idle speeds, which leads to unstable engine operation. This problem can be solved by flushing the throttle or updating the firmware, in extreme cases, drilling a hole in the throttle may be required.
In general, this engine is one of the most problematic among the Duratec models, so it is better to pay attention to the 2.0 liter engine.
Ford Duratec HE/Mazda MZR L8 1.8 and 2.0 engine numbers
The location of the engine number on a Ford Focus or Mondeo is on the rear of the cylinder block, on its left side relative to the direction of travel of the car.
Now let’s look at tuning the Ford/Mazda 1.8 liter and 125 hp engine.
Tuning
Chip tuning
Tuning offices offer firmware with an increase in power almost to the level of the older 2L model. As we know, in practice, the atmospheric engine firmware gives little or no noticeable gain. To feel a little extra hp, you need to replace the intake and exhaust together with the firmware, but it will be much more effective to inflate your engine.
Compressor on Duratec 1.8 HE
How we’re going to blow. Order blower PC-23-e (pressure 0,7 bar) for your Ford together with intercooler, injectors from Mondeo 2.3, reduce high compression ratio thickened gasket, install all this and you can drive, but that the engine flew in full growth need to look for a specialist who will calibrate the motor and squeeze out of the configuration of all the juices. After tuning you will get about 170 horses. To install a more powerful supercharger, Mercedes’ for +\-1 bar, you need to change the piston forged (see Wiseco, CP Pistons, etc.) with lower compression ratio to 8-9 +\-, MAF from Focus ST, more productive injectors from older models or others (depending on the planned power of the future engine) and inflate to 200+ hp.
