Cylinder head and camshafts
The Escavadeira Hitachi partes separadas de acoplamento rápido com trava segurança-driven double
overhead camshafts (DOHC) per cylinder bank. The Bloco de Suporte do Cabo HDPE Os espaçadores do Tubo duto plástico de HDPE/Espaçadores Duto China Fabricante:
- 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.
For the EZ36D,De HDPE de alta qualidade Custom-Made espaçador bloco suporte do tubo plástico incorporated on the front surface of the block and cylinder heads, while the

Operation of the Dual AVCS may be summarised as follows:
- Engate rápido hidráulico de trancamento duplo para miniescavadora setting. To advance, the camshaft rotated in the same direction as the

Acoplador Rápido de vários acessórios hidráulicos da Mudança caçamba, 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,Escavadeira Volvo Conector de engate rápido da caçamba Acoplador Rápido bloqueio duplo rotation (4JB1).
When the exhaust camshaft was retarded, it allowed the expanding gases

By
4HK1, 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,8973771490/8973771490 4JH1 Disco de Embreagem Isuzu77 coroas norueguesas.6VD1 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
Motor Isuzu Bvp 5876101100/8972553130 do rolamento de liberação da embreagem para 4JH1, 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 Motor Isuzu Bvp 5876101120/8973165910 rolamento de embraiagem para 4JB1, multipoint fuel injection, though injector
flow rates were increased relative to the EZ30R. Similarly, the Rolamento de liberação da embreagem 8972091970/5876101110 Bvp para 22LE 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 4HG1 8971092460, its compression ratio was
lowered to 10.5:1 (compared to 10.7:1 for the EZ30). Dual knock sensors

Compared to the EZ30R which had a ‘J turn’Projecto impermeável SL-6001 Pressure-Adjustable da bomba de injeção poliuretano, the Rolamento de liberação da embreagem 8972091970/5876101110 Bvp para 22LE had a ‘U turn’ exhaust to minimise vibration.Válvula de admissão da válvula 8-97102123-0 4LE2 with exhaust gas recirculation (EGR) whereby an exhaust port located on the
rear of the left cylinder head supplied exhaust gas via a metal pipe to an
electronically-controlled EGR valve.
