Bestchem Methanol Premix 60% (for water injection)
Note: SCDF P&FM storage licence is required if the quantity purchased, stored or kept exceed the licence exemption quantity (i.e. 20 litres for most P&FM).
Bestchem Methanol Premix (for water injection)
Water injection, also known as anti-detonant injection, is spraying water/methanol mix into the incoming air or fuel-air mixture, or directly into the cylinder, in order to cool certain parts of the induction system where "hot points" could produce premature ignition. Methanol acts as a cooling agent, increases volumetric efficiency and lower the air intake temperature dramatically, much more cooling than an intercooler. It also permits the use of very high compression ratios.
Bestchem Methanol Pre-Mix is a blend of 40% deionized water and 60% methanol. Deionized water which is also known as demineralized water (DI water) is water that has had its minerals removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionised water in laymen terms means purified process water which has most of the dissolved solids removed. Deionized water should be used in the mixture to ensure the accumulation of scale and foreign matter is eliminated, which may contribute to the accumulation of scale and foreign matter in the water injection plumbing system.
Caution: At high concentration and injection rates, methanol can act more like a fuel than a coolant. As you increase the portion of methanol injected, you are releasing more energy into the cylinder as the combined gasoline and methanol burn. You will increase the cylinder temperature rather than reducing it. Beyond 50/50 ratio, onset of detonation is more likely.
Under the Fire Safety (Petroleum and Flammable Materials) Regulations, storage and transportation of petroleum and flammable materials (P&FM) is under the Singapore Civil Defence Force (SCDF) licensing control.
Anyone who intends to store or transport petroleum and flammable materials beyond the stipulated exemption quantities are required to obtain a licence from SCDF.
If you do not possess the P&FM storage license, we request that you activate an order only when you have fully consumed the P&FM products in your premise to ensure that you do not stock P&FM products exceeding SCDF’s stipulated exemption quantity.
Best Chemical Co (S) Pte Ltd holds no responsibility for violations beyond our control. Storage and transport licence is not required if the quantity stored or transported is below the licence exemption quantity (i.e. 20 litres for most P&FM).
All storage of P&FM, regardless of quantity stored, have to comply with fire safety requirements for storage of flammable materials.
