The upper part of the valve stem, within the rocker box, is lubricated by oil. If this oil travels unchecked along the valve stem, engine HC emissions will become excessive. To control this, an elastomeric seal is fitted over the top of the valve guide. These may wear or stiffen with age, so are usually replaced whenever valves are removed for ...
The original Schrader valve design was invented in 1891 and patented in the United States in 1893. [2] The Schrader valve consists of a valve stem into which a valve core is threaded. The valve core is a poppet valve assisted by a spring. A small rubber seal located on the core keeps the fluid from escaping through the threads.
The civil war between the Nationalist Party of China (Kuomintang, or KMT for short) under Chiang Kai-shek and the Chinese Communist Party (CCP) under Mao Zedong traced back to KMT's Shanghai Massacre in 1927, which triggered Communist insurgencies such as the Nanchang Uprising and the Autumn Harvest Uprising, as well as the formation of the ...
A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s, e.g. water. [clarify]
Rings are also sprung to increase the contact force and to maintain a close seal. The spring force is provided by either the stiffness of the ring itself or by a separate spring behind the seal ring. It is important that rings float freely in their grooves within the piston, so that they can stay in contact with the cylinder. [5]
The National Revolutionary Army (NRA; 國民革命軍), sometimes shortened to Revolutionary Army (革命軍) before 1928, and as National Army (國軍) after 1928, was the military arm of the Kuomintang (KMT, or the Chinese Nationalist Party) from 1925 until 1947 in China during the Republican era.
By this time, a longer-stroked 2.3-litre 16-valve version of the engine was available alongside the original 2.0 which was still available in both 8-valve and 16-valve versions. This 2.3-litre unit also appeared in the Ford Scorpio and the Ford Transit van. The I4 remained the main petrol unit for the original Galaxy until its 2006 redesign.
The Kuomintang (KMT) is a Chinese political party that ruled mainland China from 1927 to 1949 prior to its relocation to Taiwan as a result of the Chinese Civil War. The name of the party translates directly as "National People's Party of China" or "Chinese National Party" and was historically referred to as the Chinese Nationalists.
