รู้เรื่องมาตรฐานACEA ไอเสียของผู้ประกอบการรถยนต์ฝั่งตะวันตก
A นำหน้าจะหมายถึงเครื่องยนต์เบนซินขนาดเล็ก
B นำหน้าจะหมายถึงเครื่องยนต์ดีเซลขนาดเล็ก
C นำหน้าจะหมายถึงเครื่องยนต์ที่ติดต้องอุปกรณ์ TWC หรือ DPF
E นำหน้าจะหมายถึงเครื่องยนต์ดีเซลขนาดใหญ่
ซึ่งในแต่ละส่วนก็จะมีรายละเอียดดังนี้ครับ
ACEA stands for "Association des Constructuers Européens de l’Automobile". This classification system is the European equivalent of the API classification system, but is stricter and has more severe requirements.
Hence an oil that meets both API & ACEA specifications uses a better additive package than one that is designed to meet only API specifications. Unlike the API, ACEA has three main groups – “A/B”for petrol (A) and light duty diesel (B) engines, “C” for light duty three way catalyst (TWC) and Diesel Particulate Filter (DPF) compatible oils, usually Low and Mid SAPS (Sulphated Ash Phosphorus Sulphur) and “E” for heavy duty diesel engines. These can be defined as follows.
DESIGNATION AND DESCRIPTION:
A1/B1
For use in petrol and light duty diesel engines capable of using low friction, low viscosity, and low HT/HS shear (2.9 to 3.5cP) oils. (Obsolete)
A3/B3
Stable, stay in grade oil intended for use in high performance petrol and diesel engines or extended drain intervals.
A3/B4
For use in direct injection diesel engines where special oils may be required, but also suitable for applications described under A3/B3.
A5/B5
Similar to A1/B1 but for high performance engines capable of using low friction, low viscosity as well as low HT/HS oils. May be unsuitable for use in some engines.
A7/B7
Stable, stay-in-grade engine oil intended for use at extended oil drain intervals in passenger car and light-duty gasoline & DI diesel engines designed for low viscosity engine oils with HTHS viscosity of 2.9 to 3.5 mPas. Relative to A5/B5 these engine oils provide also low speed pre-ignition- and wear protection for turbocharged gasoline DI engines as well as turbocharger compressor deposit (TCCD) protection for modern DI diesel engines.
C1
Stable, stay in grade oil for use in vehicles fitted with DPFs & TWCs and in high performance diesel and petrol engines requiring low friction, low viscosity and Low SAPS (Sulphated Ash
