ef_evap: Evaporative emission factor

Description

ef_evap is a lookup table with tier 2 evaporative emission factors from EMEP/EEA emisison guidelines

Usage

ef_evap(ef, v, cc, dt, ca, k = 1, show = FALSE)

Arguments

ef

Name of evaporative emission factor as *eshotc*: mean hot-soak with carburator, *eswarmc*: mean cold and warm-soak with carburator, eshotfi: mean hot-soak with fuel injection, *erhotc*: mean hot running losses with carburator, *erwarmc* mean cold and warm running losses, *erhotfi* mean hot running losses with fuel injection

v

Type of vehicles, "PC", "Motorcycles", "Motorcycles_2S" and "Moped"

cc

Size of engine in cc. PC "<=1400", "1400_2000" and "2000" Motorcycles_2S: "<=50". Motorcyces: ">50", "<250", "250_750" and ">750"

dt

Average daily temperature variation: "-5_10", "0_15", "10_25" and "20_35"

ca

Size of canister: "no" meaning no canister, "small", "medium" and "large"

k

multiplication factor

show

when TRUE shows row of table with respective emission factor.

Value

emission factors in g/trip or g/proced. The object has class (g) but it order to know it is g/trip or g/proceed the argument show must by T
