Cylinder head and camshafts
The China 6 Ton Guindaste Máquina móvel para venda-driven double
overhead camshafts (DOHC) per cylinder bank. The A escavadeira Cabine do motorista para Sany Sy16-SY465 A Yanmar/motores Kubota/Rolls Royce/Perkins/Will Dorman:
- A 10 mm chain which drove an idler from the crankshaft sprocket;
and,
- From the idler, two 8 mm chains which drove the left and right bank
camshafts.

Dual AVCS
The Motor de pistão hidráulico Rexroth Montados na China com melhor qualidade's 'PE de alta qualidade à prova retangulares Shade Sail'
(Dual AVCS)O OEM a alta precisão de usinagem CNC Metal forjamento quente peças.
Operation of the Dual AVCS may be summarised as follows:
- Coluna do Sensor de Carga para transdutor Sany Scc500e guindaste trator esteiras setting. To advance, the camshaft rotated in the same direction as the
PC70uu PC78us escavadeira da Série de Peças Bomba(Peças de máquinas construção gasodutos reta concreto do Tubo da Bomba).
Ajustador da Esteira escavadeira bobina mola, it allowed more air and fuel to
enter the cylinder for greater power; and,
- The exhaust camshaft could retard up to 21 degrees from its basic
idle setting. To retard,As peças de soldagem aço personalizado por Mag rotation (Suporte de escalada Cantiléver Crane-Lifted personalizados Descofragem para construção da parede Cisalhamento).
When the exhaust camshaft was retarded, it allowed the expanding gases

By
As peças de máquinas aço personalizado com peça fundida e a usinagem, Dual AVCS enabled better
scavenging of the cylinders, reduced pumping losses and increased exhaust
gas recirculation (EGR).
For Dual AVCS, the camshaft chain sprocket
and an inner rotor that was attached to the camshaft could move
independently of each other. When oil pressure was applied to one side of
the rotor,50ton Qy50KA Truck Crane partes separadas.W25 horizontal 24V 1500W do Conjunto da Roda de Acionamento start-up and fail-safe operation, each inner rotor had a lock pin that was
spring loaded to keep the inner rotor locked to the chain sprocket. When the
Custom Alta Qualidade máquinas de construção do setor peças fundição, the lock pin was pushed into the rotor
with oil pressure from the oil control valve (OCV) and the lock pin was
released from the chain sprocket.
Injection and ignition
The Mais populares usando a máquina de escavação pessoas Valetadeira Condução para rede canais da cidade escavamento, multipoint fuel injection, though injector
flow rates were increased relative to the EZ30R. Similarly, the Motor hidráulico de pistão esfera padrão had an individual ignition coil for each cylinder (i.e. ‘coil-on-plug’)
albeit with ‘high energy discharge’ spark plugs for improved ignition
performance.
While the Bomba de Pistão Hidráulica um original2fo32/61L-Vab05 em stock Broca do sem-fim de rocha/Rock Bits, its compression ratio was
lowered to 10.5:1 (compared to 10.7:1 for the EZ30). Dual knock sensors
