Oil is leaking from bank 1 and/or bank 2 at any point between the VVEL ladder assembly and the related cylinder head at sealing surface shown in Figure 1. NOTE: Figure 1 does not show the entire sealing surface that can be affected and is only an example of

CVTC and VVEL together control the valve phases and its valve events, allowing free-control of the valve timing and lift. This results in more efficient airflow to the cylinder, significantly improved responsiveness, optimizing the balance between power and environmental performance.

NISSAN's newly developed Variable Valve Event and Lift (VVEL) system for realizing unprecedented balance of responsiveness and power, fuel efficiency and low emissions.

rVVEL is a system which controls the amount of air intake directly at the intake-valve right before the combustion chamber r VVEL combined with C-VTC, creates continuous movement of valve

2009年3月12日 · a good Euro oil should serve you well. I'd go for Castrol 0W40 or M1 0W40. I don't think synthetic oil will hinder the break-in one bit, at least for both of my cars (ran syn. all their life) all showed elevated metals during the first 15000~20000mi.

2004年8月30日 · The so-called Nissan Ester oil was recommended for the VVEL-equipped engine (3.7L engine in the G37 and 370Z, called VQ37VHR). Maximas and Altimas have a different engine - 3.5L with no VVEL, so no Ester oil is needed or recommended.

2009年6月15日 · A new Variable Valve Event and Lift (VVEL) system has been developed as an effective technology for reconciling environmental performance such as lowering the fuel consumption and exhaust emissions with driving performance. This system can continuously vary both the intake valve lift and event angle

2022年3月18日 · The VVEL motors need a certain oil pressure for them to work. If you are running into timing codes and everything else checks out, meaning the crankshaft and camshaft position sensors are fine and the teeth on the flywheel are fine then chances are that your cam phasers are bad or you have the oil gallery gaskets leaking.

2016年5月13日 · vvel作用和效果. vvel技术把发动机实际的气流控制从节气门处移到了进气门口，由于控制位置更接近于燃烧位置，油门响应得到了改善。由于气门口处的控制更精确（每缸分别控制），无论是中、低负荷还是高负荷工况，动力输出都有所改善。

气门调节技术以日系车为代表：结构最为巧妙的是日产的连续可变气门升程技术（VVEL），其他厂家如丰田的VVTi,本田的VTEC，宝马的Valvetronic都大同小异。 变速箱最新技术就是采用双离合的直接换档变速器（DSG），也是大众奥迪的专利，所以保时捷后来给自己的同类产品又取了个名（PDK），俗称跑得快。 其他厂家同类产品也在陆续问世。 现在内燃机动力核心技术最先进的就属大众奥迪了。 内燃机引擎最新技术：汽油机主要有燃油直喷，分层燃烧，涡轮增压（合 …
