the Subaru Boxer 1800cc engine
Subaru Boxer Engine Production - Factory of Kiryu Kogyo
Subaru engine production plant. The famous motor EJ20 can be manufacturing. And the product line that manufactures the WRX STI EJ25 turbo for North America.
Location: 2-704 Aioicho, Kiryu City, Gunma Prefecture (Japan).
The headquarters factory of Kiryu Kogyo (a sister company that received contract manufacturing from Subaru) assembles the EJ20 engine.
The EJ20 Final Edition uses a balanced motor that reduces weight and balancing tolerances for rotating parts.
Main line flow begins with cleaning the cylinder block, which is an important part inside the engine, then assembling the crankshaft and connecting rod, and assembling the piston, cylinder head, flywheel and clutch cover.
Cleaning the cylinder block.
The cylinder block cleaning is the starting point of the main line.
In addition, about half of the complete engine is complete with a water pump, camshaft, valve clearance, spark plug, etc. From here, let's move on to individual manual work.
Particularly in the EJ system, the connection between the piston and the rod is different from other engines, so a service hole is made in the cylinder block to insert the piston pin, and this hole is the piston pin hole at the small end of the pine plunger. stock. You need to align the hole and insert the piston pin.
Crankshaft and block alignment work.A connecting rod will be combined with a 5-bearing crankshaft, which has a short overall length unique to a horizontally opposed engine. Since the horizontally opposed engine has pistons on the left and right, the cylinder head is also divided into left and right. Every part seems to show the individuality unique to horizontally opposed engines, which is different from other engines. The left and right cylinder blocks firmly sandwich the crankshaft, so the #Subaru #EJ20 turbo #engine was able to obtain high rigidity.
The complexity of this assembly process is that you will have to do all the work from the intake manifold to the fuel, water and oil lines yourself, assembling the auxiliary equipment.
It is said that each engine can be assembled in 40 minutes and there are 6 workers. In addition, the ignition test to check engine performance is also challenging, and all engines are performed on two test benches after assembly.
Piston assembly work.
The large piston is the main feature of the EJ20 turbocharger. In the EJ20, the connection between the piston and rod is different from other engines, so it is difficult to insert the pin to align with the part where the service hole is drilled in the cylinder block to insert the piston pin.
It takes about 3 hours to assemble one engine with 26 people. It will be transported by land on a special pallet on which the two engines will be mounted.
Flywheel and cover clutch assembly work.
After assembling the flywheel and clutch cover, parts and accessories will be installed around the camshaft.
Individual work process.
In individual work, all workers perform the same work, but the assembly process to be performed by that worker can be confirmed on their own monitors.
It looks like an engine. You can immediately check the detection of torque tightening work on the monitor. Each worker is notified by radio waves whether or not torque has been applied, but if the latest worker is performing the same work, there is a possibility that the radio waves will be erroneously detected. For this reason, it seems that they use radio waves with different frequencies depending on the work location. The history of synchronization and tightening, the work time required, etc. are all input to the card.
Engine oil injection and performance check process.
After installing the crankshaft pulley, the engine oil is poured into the engine. After that, they proceed to the fire test.
Under load on a test bench Visual inspection for oil leaks.
