1:24 Mitsubishi 4B11 Engine Detail Set (Resin)
4B11T was released in 2007 to replace 4G63 engine which was in production for nearly two decades. During its life span 4G63 proved itself to be a trustworthy and strong engine in every aspect. Designing 4B11T was a real challenge for Mitsubishi engineers. 4B11T should be more efficient and more friendly to environment and it should be able to cope -better outperform- 4G63. 4B11 is an inline four engine featuring dual over head cams and four valves per cylinder. Boost is generated by a single turbo charger. 4B11 displaces 1998cc with bore and stroke being both 86mm, which is also known as a square design. Reducing the overall weight and increasing the efficiency were the two major engineering problems to be solved. 4B11 block is cast aluminum with iron sleeves and employs a semi closed deck design. Aluminum is chosen for reducing weight where iron sleeves promote reliability of the engine. Use of balance shafts are avoided to reduce the overall weight even further. The engine internals are designed to cope with huge loads generated by the turbocharger. All 4B11Ts roll out of the factory with Mahle forged pistons. These pistons have cooling channels with different number of passages to the oil rings according to the intake and exhaust sides. As well as pistons the beefy rods are also capable of dealing with high loads. Rods are connected to the crankshaft with 21mm bearings to reduce the friction.
