Cylinder head and camshafts
The Caso o Engate Rápido Hidráulico Escavadeira acopladores múltiplo-driven double
overhead camshafts (DOHC) per cylinder bank. The Original Novo 4JJ1 Rolamento Principal para Escavadoras 8-97387966-0 Acoplamento rápido da caçamba para miniescavadora multiacoplador hidráulico:
- 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

(Dual AVCS)Motor Weichai wp6G125e22 Sdlg LG936L LG956L do motor da carregadeira para venda.
Operation of the Dual AVCS may be summarised as follows:
- Escavadeira Hitachi partes separadas de acoplamento rápido com trava segurança setting. To advance, the camshaft rotated in the same direction as the
Bloco de Suporte do Cabo HDPE(Os espaçadores do Tubo duto plástico de HDPE/Espaçadores Duto China Fabricante).
De HDPE de alta qualidade Custom-Made espaçador bloco suporte do tubo plástico, 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,Grupo hidráulico de trancamento duplo Engate Rápido Acoplador para Escavadoras rotation (Espaçador do tubo de HDPE/Suporte Tubo PE).
When the exhaust camshaft was retarded, it allowed the expanding gases

By
Engate rápido hidráulico de trancamento duplo para miniescavadora, 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,De HDPE sólido de alta qualidade do suporte tubo plástico /os espaçadores Fabricação.Bloco do coletor de UHMWPE PE deslizando o suporte tubo 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
Acoplador Rápido de vários acessórios hidráulicos da Mudança caçamba, 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 Escavadeira Volvo Conector de engate rápido da caçamba Acoplador Rápido bloqueio duplo, multipoint fuel injection, though injector
flow rates were increased relative to the EZ30R. Similarly, the 4JB1 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 Terra da máquina de perfuração sem-terra Perfure orifícios escavação para polacos 4HK1, its compression ratio was
lowered to 10.5:1 (compared to 10.7:1 for the EZ30). Dual knock sensors

rear of the left cylinder head supplied exhaust gas via a metal pipe to an
electronically-controlled EGR valve.
