Low-carbon alcohol clean new energy fuel additive

Abstract

The invention discloses a low-carbon alcohol clean new energy fuel additive. The low-carbon alcohol clean new energy fuel additive is compounded from methyl alcohol, butyl alcohol, isooctane, ethylcyclohexane, cyclohexane, isobutyl alcohol, petroleum ether, isohexane, methyl cyclohexane, nitromethane, ethylene glycol, liquid paraffin, methyl cyclopentane, an anti-dissolving additive, a dispersingagent, a distilling range regulator, a stabilizing agent, a compound cold starting agent and a metal surface passivator. Compared with the prior art, the low-carbon alcohol clean new energy fuel additive reduces the emission, protects the environment, improves the power, reduces the fuel consumption, clears the carbon deposit, does not need to reform an engine, is low in cost, is simple in production process, and has popularization and application values.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a low-carbon alcohol clean new energy fuel additive. Background technique [0002] Low-carbon alcohol fuel is a fuel mainly composed of alcohols (such as methanol, ethanol, butanol, etc.). It is a liquid renewable new energy. It is also a kind of biomass energy. Like nuclear energy, solar energy, wind energy, and hydraulic energy, it is an environmentally friendly and clean energy that governments are vigorously promoting at present; facing the depletion of petrochemical energy, alcohol-based fuel is the most potential new alternative energy. It is favored by business organizations from all over the world. According to the existing national standards, when the engine (including gasoline engine and diesel engine) is manufactured, it follows the gasoline standard. %. Low-carbon alcohol clean new energy itself has an oxygen content of 35-45%, which is both an advantage and a disadvantage. The...

Problems solved by technology

The disadvantage is that the low-carbon alcohol clean new energy has a high oxygen content. When burning, it first consumes its own oxygen and cannot consume all the oxygen in the air. As a result, when the exhaust gas is emitted, the oxygen sensor at the rear of the vehicle detects that the residual oxygen content is too high (that is, monitoring The value of gas is relatively lean), so that the oxygen sensor will send an alarm to the on-board computer ECU, thereby extending the fuel injection pulse width (that is, prolonging the fuel injection time of the engine's multi-point EFI system, which is also the reason why the new fuel is slightly more fuel-intensive than gasoline), but Even so, the actual air-fuel ratio of low-carbon alcohol clean new energy is still less than 14.7 (at present, the air-fuel ratio range of gasoline vehicles is roughly 11-20, and the air-fuel ratio of low-carbon alcohol clean new energy is about 6.0-8.0), which cannot be adjusted to the needs of gasoline. In the air-fuel ratio range, the residual oxygen content in the exhaust gas still exceeds the standard, at this time, the engine warning light will be on

But this is not a problem of unqualified low-carbon alcohol clean new energy, nor does it cause any damage to the engine. It is caused by the fact that the actual air-fuel ratio is inconsistent with the theoretical air-fuel ratio of existing gasoline engines.
