Kpd rakan semua yang inginkan artikel ini dalam BM, harap sabor ye... sibuk sket ni....
crossplane ni teknologi lama sebenarya, tapi pertamakali digunakan untuk motosikal 4 selinder. Kebiasaannya, aci oleng atau crankshaft tu sebaris atau sejajar je keempat empat pin nya, kalau dilihat dari pandangan sisi, tapi bagi enjin crossplan atau jajar-lintang ini, ianya bertentangan 90° .
For the first time, the cross plane crankshaft is utilised on an in-line 4 cylinder motorcycle engine. The 2009 Yamaha YZF-R1 uses the crossplane crankshaft and also utilises a specially designed balancer to counteract the unusual vibration found in this type of crank when not used in conjunction with a V8 engine. This type of crank has been used in their M1 moto GP racing models for 4 years, and has finally made it to mass-production due to advances in Yamaha's metal forging technologies.
The crossplane or cross-plane is a crankshaft design with a 90° angle between the cylinder banks.
The crossplane crankshaft has four crankpins, each offset at 90° from the adjacent crankpins. The crankpins are therefore in two planes crossed at 90°, hence the name crossplane. A crossplane crank may have up to five main bearings, and normally does, as well as large balancing weights. Crossplane engines have uneven firing patterns within each cylinder bank, producing a distinctive burble in the exhaust note, but an even firing pattern overall.
Early V8 engines, modern racing engines and some others used or use the flatplane crankshaft, which is similar to that used in a straight four or flat-four engine. Flatplane engines may use any angle between the cylinder banks, with 60° and 90° the most common, however Ferrari uses 65°. They lack the V8 burble and the inherent mechanical balance of the crossplane design, but do not require the large crankshaft balancing weights. Modern flatplane designs often incorporate a balance shaft, which is not needed by the crossplane design.
The crossplane design was first proposed in 1915, and developed by Cadillac and Peerless, both of whom produced flatplane V8s before introducing the crossplane design. Cadillac introduced the first crossplane in 1923, with Peerless following in 1924.
