IKCO EF engines
Encyclopedia
IKCO
EF engines are four cylinders engines. The EF7 series are designed jointly by Iran Khodro Powertrain Company
(IPCO) and F.E.V GmbH of Germany. The other models will be designed by IPCO itself. IPCO is the powertrain
designing & producing company of Iranian car manufacturer Iran Khodro
(IKCO). IKCO aims to supply 800,000 powertrains by 2010.
The first phase of IKCO EF Engines project (EF7 Dual-Fuel) investments were about 80 million US$.
EF4 & EF7 engines use CNG
as their main fuel and they can also use gasoline.
EFD is the first engine of the EF family that is single-fuel. It uses high quality diesel (Euro 4 Quality or better) as fuel.
EF engines share most of their parts between them. It was IKCO's aim to reduce costs & providing ease of supplying the parts in the future for after sales services.
The EF family dual-fuel & petrol-fuel engines have achieved the Euro IV emission standard and are able to achieve Euro V emission standard with some minor changes but EFD will be the first engine of the family which comes with the Euro IV emission standard as its first release, and is able to achieve the Euro VI emission standard with some changes.
The most important suppliers for EF engines are INA
for sensitive VVT
parts & some other mechanical parts, MAHLE
which supplies some important parts of the engine family such as Pistons, with Bosch
supplying the ECU
and electrically controlled pedal and lots of other important sensitive electronic parts. Almost all of the parts (except high-tech & sensitive parts) from World wide well known companies (As mentioned) are producing in Iran under license with the highest required quality for the engines.
Also The German
company Bosch
had shown interest in assembling the Iranian engine under license. In 2008 IKCO has announced that EF7 is among 3 best CNG-based engines of the world in designing.
, Germany
, it was a 16-valve engine mobilized with CVVT
technology on its intake valves (IPS kind).
It features an advanced cooling system (Including lubrication and water cooling) compared to lots of same-level new engines in the world & also the TU5JP4 (The EF7 is mobilized with direct driven oil pump). The water pump, oil pump and oil coolant system are all integrated in one place to remove two other parts of the engine compared to lots of other engines. Some other unnecessary parts are removed to reach the goal providing an ease to change the oil filter.
The engines will use a Three way Catalytic Converter to reach higher emission standards.
All the EF7 variants have passed the NVH tests successfully on their head cylinder & cylinder block.
Also, the engines have a Blow-by system which does ventilation for the Crankcase
and Oil Pan.
The EF7 assembly line is in Tehran

and petrol using conditions.
The engine has an amazing timing belt change interval of 180,000 Km as IKCO has announced. IKCO has guaranteed that if the engine runs only on CNG it won't need any special maintenance until 250,000 km(average) and if the engine runs with both CNG and gasoline the number will increase to more than 250,000 km.
Due to lack of possibility and so many requests for single-fuel Samand with EF7 engine and lack of readying the EF7 Petrol-Based engine, In late 2009 IKCO wanted IP-CO to start a project for removing CNG-necessary parts of the engine. So the project done in about 3 months and tests completed in 2nd quarter of 2010. In this version of engine, only ECU Program is changed & CNG functions are disabled; This ECU program supports immobiliser too.
Currently, consumers are able to purchase Samand EF7 single-fuel.
In September 2010, IKCO announced the design and production of a modified EF7 engine with reduced fuel consumption & air pollution. The engine is mobilized with Direct Injection technology for both petrol & CNG.
As the IPCO president says after the new engine is produced, IKCO will be the first manufacturer in the world using the Direct Injection technology for CNG engines.
In fact, with the completion of the project a new kind of direct injection technology will be introduced which will be called CNG direct injection.
To resist to the high temperature of the engine combustion there will be about 35 kg of nickel
used in the cylinder block alloy.
In addition, a new lubricant will produce for the engine by the Company, Behran Oil.
IP-Co has estimated the engine's life cycle to be around 10 years.
The project of the new engine is currently on its first phases and at the end, there will be an EF7 fully compatible with gasoline.
The new engine will name EF7NE(maybe the name changes in the future) and will have many changes compared to the EF7 dual-fuel engine. Some of the changes will be: Reducing the engine compression ratio from 11:1 to 10.5:1, replacing parts that are resistant & compatible to high temperature of combustion of CNG
with parts with weaker resistance to reduce production costs(New parts are fully compatible with the temperature rising from combustion of petrol) and some other changes
In addition, EF7NE will use a newer ECU program and functions
Another changed part of the engine compared to his father EF7, will be the catalytic converter
. The change is due to making the engine to petrol-based and there is no need to use a CNG-compatible catalytic converter for the engine.
The engine output is estimated to be between 118 PS-126 PS. It depends on the company strategy, decisions & plans.
It is expected that the engine will be shown to the public in mid 2011.
The engine reaches maximum power at 6000 rpm and the maximum torque at 3250 rpm for both CNG
and petrol.
It shares almost all of its technologies with the big brother, EF7.
The EF4 assembly line will be in Esfahan, Iran
.
It's a 16-valve engine featuring lots of new diesel engines technologies.
Because EFD engines are the first engines from the family which are using a different fuel, this makes a necessity for changing most parts which means there are just some parts of other EF family engines used in them.
Since the initial talks about the project in mid 2008, NIOPDC
was the main sponsor of the project (EFD) and has supported the project up to 20 million US$.
Because Iran Khodro
had never designed a diesel engine before the EFD engines and the company wanted to design diesel engines with the properties of being modern, technological and comparable with other new diesel engines in their range, Iran Khodro
made a partnership in designing the engines & consulted with AVL
in many aspects for gaining the new required technologies to reach to the goals.
IP-Co says production of the non-Turbocharged EFD engine costs about 1.7 times more than other EF family engines; but if a costumer buys a car using the engine, after not a long time, these costs will be paid back to the consumers due to less fuel consumption and less maintenance needs.
Due to being old and inefficiencies of the Peugeot
BE3/5 gearbox and also a necessity for having a new gearbox for other IKCO
engines, the company started to design a new gearbox which can be used for the EFD engines.The gearbox will overcome the high torques and will have more efficiency compared to the BE3/5 gearbox.
On November 30, 2010, IKCO
announced they will finalize the gear ratios of the new gearbox for EFD in the near future.
Here are IP-Co reasons for starting the design of a diesel engine (EFD engines):
These are some of the technologies that are used in implementation of EFD engines:
and mobilized with mentioned technologies listed above.
The engine reaches its maximum power at 4000 rpm and maximum torque at 1750 rpm.
It is currently installed on some Samands and Soren
s to pass the last required tests.
Other specifications are listed in the Performance section blew.
IP-Co has no plan to develop it until its brother, EFD comes to the market but it is noticeable that the project is near to be finished.

EFD engines
EFD diesel engines have a displacement of 1497 cc with a bore of 76 mm and a stroke of 82.5 mm.It's a 16-valve engine featuring lots of new diesel engines technologies.
Because EFD engines are the first engines from the family which are using a different fuel, this makes a necessity for changing most parts which means there are just some parts of other EF family engines used in them.

in many aspects for gaining the new required technologies to reach to the goals.
IP-Co says production of the non-Turbocharged EFD engine costs about 1.7 times more than other EF family engines; but if a costumer buys a car using the engine, after not a long time, these costs will be paid back to the consumers due to less fuel consumption and less maintenance needs.
