1. JASO M345 (moteurs \u00e0 deux temps)
Introduite en 1994, cette norme \u00e9value les huiles pour moteurs \u00e0 deux temps en termes de lubrification, de propret\u00e9, de fum\u00e9e d'\u00e9chappement et de blocage du syst\u00e8me. Les huiles sont class\u00e9es\u00a0FB<\/strong>,\u00a0FC<\/strong>et\u00a0FD<\/strong>\u00a0(performances maximales, \u00e9missions minimales).<\/p>\n<\/div>\n

2. JASO T903 (moteurs \u00e0 quatre temps)
Lanc\u00e9e en 1998 et mise \u00e0 jour en 2023, la norme T903 garantit que les huiles pour moteurs \u00e0 quatre temps r\u00e9pondent aux exigences en mati\u00e8re de friction des embrayages, de performance du moteur et de viscosit\u00e9. Elle comprend\u00a0MA<\/a><\/strong>\u00a0(motos \u00e0 embrayage humide) et\u00a0MB<\/a><\/strong>\u00a0(scooters avec CVT).<\/p>\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

The\u00a0Japanese Automotive Standards Organization (JASO)\u00a0is a key player in Japan\u2019s automotive industry, setting standards for vehicles, components, and lubricants to ensure quality, safety, and performance. As part of the\u00a0Society of Automotive Engineers of Japan\u00a0(JSAE), JASO drives innovation and global compatibility. This article explores JASO\u2019s role, standards, and impact, optimized for search engines. What is JASO\u2014Japanese Automotive Standards Organization JASO, under JSAE, establishes technical standard for automotive components, with a focus on\u00a0engine oils for motorcycle\u00a0and\u00a0small engine. Based in Tokyo, it promotes safety, efficiency, and environmental sustainability, aligning with international standards like ISO. JASO Standard 1. JASO M345 (Two-Stroke Engines)Introduced in 1994, this standard evaluates two-stroke engine oil for lubricity, cleanliness, exhaust smoke, and system blockage. Oils are graded\u00a0FB,\u00a0FC, and\u00a0FD\u00a0(highest performance, lowest emissions). 2. JASO T903 (Four-Stroke Engines)Launched in 1998 and updated in 2023, T903 ensures four-stroke oils meet clutch friction, engine performance, and viscosity requirements. It includes\u00a0MA\u00a0(wet clutch motorcycles) and\u00a0MB\u00a0(scooters with CVT). Global Impact and Harmonization JASO collaborates with ISO and UNECE to align standards, supporting Japan\u2019s automotive exports (2.9% of GDP). The\u00a0Japan Automobile Standards Internationalization Center (JASIC)\u00a0aids this through resources like the\u00a0Automobile Type Approval Handbook. Why JASO Matters Performance: Enhances engine efficiency and durability.Environment: Promotes cleaner emissions.Consumer Trust: Certified oils ensure reliability.Industry Efficiency: Streamlines manufacturing. Conclusion JASO ensures Japan\u2019s automotive industry maintains high standards, benefiting manufacturers and consumers globally.<\/p>","protected":false},"author":1,"featured_media":6782,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[40,39],"tags":[105],"class_list":["post-6779","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-oil-academy","category-market-insights","tag-jaso"],"_links":{"self":[{"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/posts\/6779","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/comments?post=6779"}],"version-history":[{"count":1,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/posts\/6779\/revisions"}],"predecessor-version":[{"id":15766,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/posts\/6779\/revisions\/15766"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/media\/6782"}],"wp:attachment":[{"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/media?parent=6779"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/categories?post=6779"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/terzooil.com\/fr\/wp-json\/wp\/v2\/tags?post=6779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
