Engine parts operate under various speed and temperature conditions. Therefore high reliability component is necessary to handle hundreds thousands kilometers drive.
Valve trains and turbo component bring significant impact on engine performance.
Fuel system component operates under high pressure
Balance shaft rotates at 2 times faster than the engine speed
various aluminum parts used in various portions,
With pro-active technical proposal and precision quality, OTICS engine components are being adopted by various auto-maker to meet high power output, low fuel consumption and low emission requirement.
Through rolling contact with the camshaft, the roller arm controls the opening and closing of valve.
OTICS roller arm is widely used by small to large engine. Using OTICS's proprietary press technology, we can produce lightweight and compact design while maintaining high rigidity to meet the requirement of high speed, low friction, space saving, as well as cost efficient production parts.
Maintaining consistent valve lift curve is important to achieve high performance, low-emission and improve fuel economy.
To achieve this, OTICS Roller Arm is supported with Hydraulic Lash Adjuster (HLA) has the ability to keep "zero" tapper clearance typically appear upon temperature change or mechanical wear.
And it also improve noise level of engine
OTICS offer various type of HLA to respond wear resistance, high rotation speed and so on.
Valve lifter transfer the motions of cam lobe to open and close the valve.
Due to its simple, light weight and high rigidity structure, it can be apply on both high performance or compact engine.
We have various line-up of valve lifter ranging from low friction by surface treatment, built-in HLA for OHV engine and fuel pump driven type.
Variable valve lift system changes the amount of valve lift and/or timing transmitted from camshaft selectively or continuously upon activation.
By adjusting the valve characteristic to its optimum condition, it is possible to achieve conflicting functions of improving engine performance and reducing fuel consumption.
Fuel delivery pipe supplies gasoline to injector, and OTICS mainly produces fuel delivery pipes for gasoline direct injection engine.
Gasoline direct injection engine achieves clean emission by injecting fuel at high pressure to be burn at lean air-fuel ratio.
Therefore, it is necessary to have the strength to contain fuel pressure of more than 20 MPa.
In addition, its surface is treated to withstand bio gasoline or salt damage.
Instead of fuel delivery pipe, direct injection diesel engine utilize Common Rail to supply fuel to the injector.
Higher strength is required to contain extremely high fuel pressure of more than 150 MPa.
The injector holder is an important part to seal the fuel, and is a part to hold an injector to inject fuel for burning the soot stuck in the particulate filter.
Balance shaft is an important part that reduces engine's noise and vibration to maintain a comfortable cabin environment.
In order to counteract vibration caused by reciprocating motion of piston, this component rotate with imbalance weigh that generate high radial force. Therefore, high rigidity and wear resistance is required.
OTICS produces balance shafts for 3-cylinder and 4-cylinder engines. With vast experience in product development and production engineering ability, we can respond to various customer's needs.
Compressor housing gathers the high velocity air accelerated by its internal impeller into compressed air.
High efficiency and low cost are made possible by 2 piece structure using a combination of gravity casting and aluminum die casting.
The raw material consists of 2 pieces. (Patent registration)
The water-cooled compressor housing cools the wall of air flow path to prevent carbon deposits from oil mist supplied along with high temperature exhaust gas.
This product utilizes a split structure to form a water-cooled part, and a convex shape is designed at the press fit section to form the water seal by plastic flow.
We responded to a customer's request to assemble the compressor housing inlet/outlet port piping in parallel.
This product applies a split structure, and the outlet port is formed by the compressor housing main body and the modified R Piece. A compressor housing with good mounting and assembly performance has been developed at low cost.(Patent granted)
The tip clearance between compressor housing and impeller is kept at minimum to improve compressor efficiency.
The abradable seal directly injected into the shroud ring is less aggressive to the impeller and has excellent machinability characteristic.
Main function of the cam housing and cam cap is to support the camshaft that drives the intake and exhaust valves of the engine. High precision machining is required for the bearings component.
It forms part of the engine oil channel and supplies oil to various parts.
In addition, it also holds parts such as fuel pump and is designed with consideration for strength, rigidity, vibration and noise.
